Flexible Keyboard - just like in Die Hard 4

For all the die hard gadget fans!!! Yeah the words at the first line mean differently.
For all the people who saw Die Hard 4 , there was a keyboard that is flexible enough to wrap, fold, just like a paper and keep it in pocket. Assuming its untrue and just a filmsy trick, people tend to fantasize it in future. But but but.... the future has arrived so early.
Thanks to Yahoo!! They have come up with a new keyboard similar to that in the movie - The yahoo flexible keyboard. Just zip it and keep it anywhere in your carry bag or your pockets. At a price of 52 dollars. That isnt a bad deal, not at all.
To have it in your pocket click here
It sure says either scientists are motivated by these movies or these movies steals the futuristic ideas of these scientists. Starting from the very old movies , James Bond.. was the first in the series to show such things. And later they all came into existence. Its going on for real.
Great going Yahooooooooooooo!!! .

Microsoft Direction Puzzle

The puzzle was posed by Microsoft as a challenge. Looks pretty simple though you have to have a knowledge of directions. Puzzle looked almost as simple as a high school guy can do but it was got wrong my most of the people.
No, its not at all a trick question , very logical , very interesting.
Lets go for it
How many distinct points are there on the surface of the Earth from which you can walk one mile due South, then one mile due East, and then one mile due North, and end up at the same exact spot from which you started?
Give yourself a complete jerk and think about every possibility. It surely is a great question!!

Einstein's Words - Truly a puzzle

I wondered when i read those words whether the great great Mr. Einstein were a scientist or a poet whose literature is as strong as his Physics or Chemistry. He sure was genius. The quotation is as follows:
Nature shows us only the tail of the lion. But I do not doubt that the lion belongs to it even though he cannot at once reveal himself because of his enormous size.
It kept me puzzled until i knew the correct meaning. Now that you have read the quotation, try and interpret the meaning of the quotation. This really acted like a riddle. The use of English , the combination of words. When he said "I do not doubt" i started wondering what let a legendary being say this.
I thought it as a work of literature , read it word by word , try to take the meaning of combination of words as a work of art. This was my interpretation until i knew the context of these words.

I feel he wants to say that "he don't doubt his thinking to complete the natural mysteries even when nature cannot reveal itself completely because of its vast outspread belongings (that are vast in themselves)"

He encompassed a few things in one line :
  1. Nature hides the true picture of everything.(shows us only the tail )
  2. The vastness of nature is not limited to itself. Even the smallest looking thing ( tail of the lion) in nature is huge. Its vastness is hidden (shows us only the tail)
  3. Its revelation is not easy (once reveal himself because of his enormous size) and takes time even for the smallest looking thing (tail of the lion ).
  4. He never doubts(do not doubt that the lion belongs to it) himself to guess or better say reveal the hidden things behind the smallest looking things (no doubts on his confidence!!!).
As soon as i searched for it on the net. I wondered how a context can change the meaning so dramatically. The first wonder was when the search result was about the 11th dimension , i was dumbstruck for i have heard only about 4th dimension what about 11th??

The quotation was actually his response to a initiative taken by scientists where they wanted to cover all the laws and principles they made under one single theory called as "Theory of Everything". He
literally stumped all of them by saying this. Now it is

" The tail" is what we see in nature , which can be described by the four fundamental forces -gravity, electromagnetism and the strong and weak nuclear forces. The lion is the ultimate theory that will unify them in one short equation.

Woaaa that is a genius...
Now there came hurdles and discrepancies regarding it, and that is not the point of discussion. The hunt was started by him and later to capture this lion he was lost but none could even now integrate all of them under one single theory
Its just the genius of Einstein and "as many meanings as many brains".
The finest of articles on it ... Into the Eleventh Dimension

Harry Potter and the Deathly Hallows (Summary) by Rowling

The Plot/Review of the book - Harry Potter and the Deathly Hallows (Book 7) by J.K.Rowling:

The starting of the END
The final book begins with Voldemort and his Death Eaters at the home of Lucius Malfoy. They are beginning to plan out how to kill Harry Potter before he can be hidden again. After borrowing Lucius's wand, Voldemort kills his captive, Professor Charity Burbage, teacher of Muggle Studies at Hogwarts for teaching the subject and suggesting that the end of pureblooded wizards was a good thing.

Harry, meanwhile, is getting ready for his trip and reading an obituary of Albus Dumbledore; it is revealed that Dumbledore’s father, Percival, supposedly hated non-wizards and had killed several Muggles, and had died in Azkaban for his crimes. Harry regrets not having asked Dumbledore more about his past, but this is soon forgotten as he is leaving his home that night. He convinces his aunt Petunia, uncle Vernon, and cousin Dudley that they need to leave as well to avoid being captured by the Death Eaters, and eventually they leave escorted by a pair of wizards, though not before Dudley admits that he cares about Harry.

Soon thereafter the Order of the Phoenix arrive with a plan to sneak Harry away from his house without Voldemort capturing him. Ron Weasley, Hermione Granger, the Weasley twins, Fleur Delacour, and Mundungus Fletcher take a polyjuice potion to make themselves look like Harry and each depart with a different member of the Order of the Phoenix. Harry departs with Hagrid and, after being chased by Death Eaters and Voldemort, narrowly escape to the Burrow. There, the casualties are counted; Hedwig, Harry’s owl, was struck by a killing curse; George Weasley lost an ear, and Mad-Eye Moody was killed by Voldemort himself. Harry later has a vision regarding his escape; his wand had reacted with Voldemort’s borrowed wand, destroying it, and he has a vision of Voldemort questioning Ollivander, the wand maker, about why it happened.

The Will of Albus Dumbledore
A few days later the Minister of Magic arrives at the Weasley residence to give Harry, Ron, and Hermione what Dumbledore had willed to them: a Deluminator for Ron (known as a "put-outer" in previous books), with the power to douse all the lights in a room; a book of children’s stories to Hermione; and Godric Gryffindor’s sword and the first snitch Harry had ever caught to Harry. The sword, however, was withheld because, the minister claimed, it was not Dumbledore's to give. The three try to discover the purpose of the objects being given to them, but are unable to figure it out before the wedding between Fleur Delacour and Bill Weasley the next day.

Harry disguises himself for the wedding, but during the wedding they all receive a message; Voldemort has taken over the Ministry of Magic. Harry, Ron, and Hermione all flee the wedding, first fleeing to a Muggle cafĂ©. Though they think themselves safe for the moment, two Death Eaters find them almost immediately and attack them. Harry, Ron, and Hermione manage to defeat the Death Eaters, but thinking themselves in danger in public, flee to 12 Grimmauld Place, Sirius Black’s home, where they hide themselves. The group realizes that Regulus Arcturus Black was the R.A.B. from the amulet Harry found with Dumbledore, and begin searching the house for the Horcrux. Kreacher, after a bit of persuasion, tells the trio that he had helped Regulus in assisting Voldemort to place the locket horcrux in the cave. After Regulus became disenchanted, however, he ordered him to return to the cave such that he could substitute a fake locket for the real one, however, he is killed in the process. Eventually they realize that Mundungus Fletcher stole the amulet and send Kreacher to find Fletcher and bring back the amulet. Kreacher finds Fletcher, but he has already given the amulet away to Dolores Umbridge.

After a month of spying on the Ministry of Magic, the trio try to infiltrate it in order to retrieve the Horcrux from Dolores Umbridge. They ambush three wizards and use polyjuice potion to impersonate them. They discover the Ministry of Magic has changed considerably; Muggle-born wizards and witches are being rounded up openly and the Ministry itself is demonstrating its superiority over the muggle-borns. The three discover Mad-Eye Moody’s eye has been taken by Umbridge, so they take it; they then knock out Umbridge and take the horcrux from her, freeing a number of muggle-born wizards and witches in the process and encouraging them to flee the country. However, in the process their hiding place is discovered and they are forced to flee to the countryside, moving from place to place, never staying anywhere too long.

Godric’s Hollow
After several months of moving around they overhear a conversation wherein it is revealed that Godric Griffindor’s sword is actually a fake, and someone did something with the real sword. Harry hears this and is heartened, and after questioning the portrait of Phineas Black, he discovers that the sword had last been used by Dumbledore to destroy another Horcrux, the Gaunt’s ring. However, Ron feels this is just another thing for them to do and, having been injured in their escape from the Ministry of Magic, he gets in an argument with Harry and leaves, leaving Harry and Hermione together. The two are greatly saddened, but eventually realize they have to go to Godric’s Hollow on the off-chance Dumbledore left the sword there for them.

Arriving in Godric’s Hollow, the two first visit the memorial to Harry’s family, then the graveyard, where both Harry and Dumbledore’s families are buried. After laying a wreath on Harry’s parents’ grave, they encounter the old woman Bathilda Bagshot, an old family friend of Dumbledore’s who authored The History of Magic. Thinking she may have been entrusted with the sword, they follow her to her house, where they find a picture of the dark wizard Grindelwald, Bagshot’s relative and once, long ago, Dumbledore’s childhood friend. However, it is actually a trap; “Bagshot” is actually Nagini, Voldemort’s snake familiar, and Harry and Hermione only narrowly escape from Voldemort, accidentally destroying Harry’s wand in the process.

On the run for a few more days, eventually a doe patronus appears on the edge of their camp and leads Harry to Godric Griffindor’s sword, hidden in a frozen forest pool. Harry strips down and dives down after the sword but the locket Horcrux responds poorly and tries to strangle Harry. Ron returns and saves Harry from drowning, pulling the sword out of the pool in the process. The two then destroy the Horcrux with the sword and return to camp. Hermione is less than pleased with Ron and his return, but had discovered their next step: to speak to Xenophilius Lovegood and ask him about Grindelwald's mark, a symbol which has shown up time and again during their journey.

At Lovegood’s home, Harry, Ron, and Hermione are told an old wizard story about three brothers who bested death, and each had received a magical item for it – an unbeatable wand (called the Elder Wand), a stone which could bring back the dead (the Resurrection Stone), and an Invisibility Cloak that never failed with age. Harry believes that his own cloak is the Invisibility Cloak, and is very excited, but soon discovers that Lovegood has betrayed them to the Ministry; Luna, his daughter, has been taken captive and he believes that giving them Harry Potter would cause them to free her. The trio barely escape from the wizards sent to fetch them, but Harry is emboldened and believes that they need to collect all the Deathly Hallows, these artifacts given by Death, to defeat Voldemort.

The Deathly Hallows
A few weeks later, the three are still no closer to finding the Deathly Hallows or more Horcruxes. They finally manage to tune into a rogue wizard radio broadcast, run by people they know which gives news on what is really happening. However, Harry accidentally says Voldemort’s name and Voldemort’s followers, having jinxed the name, find Harry, Ron, and Hermione and capture them, taking them to Lucius Malfoy’s home. There, Hermione is tortured and interrogated by Bellatrix Lestrange to find how she acquired Godric Griffindor’s sword, believing it to have been stolen from her vault, while Harry and Ron are imprisoned in the basement with Dean Thomas, Griphook the goblin, Ollivander the wand maker, and Luna Lovegood. Harry asks the broken fragment of mirror he has for help and Dobby appears to help him, freeing them. Dobby saves Dean and Ollivander, but they have made too much noise and Wormtail is sent to check on the prisoners. Harry and Ron subdue him, and Wormtail resists strangling Harry. Ron takes away Wormtail’s wand and Wormtail’s artificial arm, made by Voldemort, strangles its owner to death for the mercy he’s shown. Ron and Harry, helpless to aid him, rush upstairs to save Hermione with the help of Dobby. They escape as Voldemort is close to arriving, but Dobby is slain by Bellatrix Lestrange as they flee.

After burying Dobby, Harry and his friends begin planning anew. Harry questions Ollivander about the Elder Wand, and chooses not to try and prevent Voldemort from acquiring it from the tomb of its last owner, Dumbledore. Instead, he questions Griphook about how to break into Gringott’s, and in exchange offers him the goblin made sword of Godric Griffindor. After extensive planning, the group goes to Gringott’s to see if they can find one of the horcruxes in the Lestrange vault; Hermione poses as Bellatrix Lestrange, Ron is disguised, and Griphook and Harry go in under the Invisibility Cloak. They manage to penetrate the traps and find the horcrux, Hufflepuff’s cup, but Griphook betrays their presence and flees with the sword. Harry, Ron, and Hermione narrowly escape on the back of a captive dragon, but Voldemort discovers at long last that they are seeking out his horcruxes.

Harry has a vision shortly after the escape; he can see from Voldemort’s eyes and hear his thoughts. Voldemort lists off all the locations of the horcruxes, realizing now they are being sought after and destroyed. Voldemort inadvertently reveals that the final horcrux, which Harry suspects to be a relic of the founder of Ravenclaw, is safe within Hogwarts. Harry realizes that if they want to get the Horcrux within Hogwarts, they need to do so immediately, before Voldemort finds his other horcruxes missing, and the trio immediately head to Hogsmeade to find a way to sneak into their old school.

The End of Voldermort
At Hogsmeade, Harry and friends are cornered by Death Eaters and saved by Aberforth Dumbledore. Aberforth opens a secret passageway to Hogwarts, where Neville Longbottom greets them. After saving Draco Malfoy's life, Harry finds Ravenclaw's Diadem in the room of requirement and it is destroyed. Harry, Hermione and Ron go to the Shrieking Shack, where they see Voldemort kill Snape, believing this will transfer the Elder wand's power to him. As he dies, Snape gives up memories to Harry, which reveal that Snape was on Dumbledore's side, motivated by his lifelong love of Lily Potter. Snape was asked by Dumbledore to kill him if the situation demands it; the curse placed on the horcrux ring limited his life, regardless. Furthermore, Harry is the final horcrux and needs to die before Voldemort can be killed. Resigned to his fate, Harry sacrifices himself to Voldemort, and is seemingly killed, but finds that the spell destroyed the part of Voldemort's soul he had inside himself. After Nagini is killed by Neville, Voldemort is killed by attempting to use the Elder Wand when his Death Curse against Harry is deflected back at him by the Elder Wand itself.

In the story's epilogue, taking place 19 years (2017) after the Battle of Hogwarts, Harry and Ginny Weasley have three children named James, Albus Severus, and Lily. Ron and Hermione have two children named Rose and Hugo. Draco has a child named Scorpius. They all meet at King's Cross, about to send their children to Hogwarts at the beginning of term. It is revealed that Harry's scar has not hurt since the Dark Lord's defeat, and there, the story ends.

Solution to Drunk for free Puzzle

The solution for the puzzle posted on 20th June 07 "Drunk for free Puzzle"
The puzzle attributed to drinking of wine without paying anything and you can do that any number of times forever
To view the puzzle click here :- "Drinkers Paradise - The Border , Drunk for free"
Sounds surely a drinkers paradise.Lets look at the reasoning:

There is nothing much to think about the situation. If you know anything about the currency values i.e. that each currency have a different value. So is the case here, at the US and Canadian border their corresponding dollars are discounted by 10 cents. It is nothing but the appreciation caused to a currency while it move from one country to another.
Actually they apparently paid for all the wine they drank. Every time they move from one country to another the value of the corresponding currency(dollar) increased. So the gain they had because of movement to and fro is paying for the wine.

Moral of the story : Nothing comes for free, not even the free looking wine. :D

Internet Error codes

Are you an internet user?? Ohh sure you are because you are reading this.
Ever wondered what all the errors mean that come by , while you are browsing your favorite sites. You saw it working fine and in a few moments with your next click something alien pops up saying error 50o etc encountered. Lets go ahead looking for the reasons and explanations for the same.

Internet Error Codes
Here are the most common codes and messages you're likely to see on your Web browser (HTTP), when accessing Usenet, using e-mail, or using the FTP protocol to upload or download files.
The codes can generally by grouped as follows -
100-199 - Information Codes. Provide information about the request or the servers involved.
200-299 - Success Codes. Indicate that the request was accepted or the requested file has no content (empty).
300-399 - Redirects. Requested content has moved.
400-499 - Client Errors. Cannot find content or you don't have the correct permissions to access it.
500-599 - Server Errors. There is a problem at the server end stopping the request from completing successfully.
To give you a greater understanding of these errors, here is a list of the most popular codes.
As a rule of thumb, the first thing you should if you get an error is make sure that you have typed in the URL or page address correctly.
Bad request 400
The request could not be understood by the server due to bad syntax. You should not repeat the request without modifications.
Unauthorized 401
The creators of a Web page may want only certain people have access to that page. You should only retry the request if you know that you have authorization.
PaymentRequired 402
This message gives a specification of charging schemes which are acceptable. You may retry the request with a suitable ChargeTo header.
Forbidden 403
The request is for something forbidden. Authorization will not help. This status code is commonly used when the server does not wish to reveal exactly why the request has been refused, or when no other response is applicable. (The file needs to be set with "read permissions" for all users.)
Not found 404
The server has not found anything matching what you requested. Make sure that the Web address (URL) that you typed in exactly matches the address you were given. Check that the capitalization matches, spelling, and punctuation, like dots (.) and slashes (/), are correctly placed. Be sure you are using the forward slash (/) and not the backward slash (\).
405 Method Not Allowed
The method specified in the Request-Line is not allowed for the resource identified by the request. The response must include an Allow header containing a list of valid methods for the requested resource.
406 Not Acceptable
The resource identified by the request is only capable of generating response entities which have content characteristics not acceptable according to the accept headers sent in the request.
407 Proxy Authentication Required
This code is similar to 401 (Unauthorized) , but indicates that you must first authenticate yourself with the proxy. The proxy must return a Proxy-Authenticate header field (section 14.33) containing a challenge applicable to the proxy for the requested resource. You may repeat the request with a suitable Proxy-Authorization header field (section 14.34). HTTP access authentication is explained in section 11.
408 Request Timeout
The client did not produce a request within the time that the server was prepared to wait. You may repeat the request without modifications at any later time.
409 Conflict
The request could not be completed due to a conflict with the current state of the resource. This code is only allowed in situations where it is expected that the user might be able to resolve the conflict and resubmit the request.
410 Gone
The 410 response is primarily intended to assist the task of web maintenance by notifying the recipient that the resource is intentionally unavailable and that the server owners want remote links to that resource be removed.
411 Length Required
The server refuses to accept the request without a defined Content- Length. The client may repeat the request if it adds a valid Content-Length header field containing the length of the message-body in the request message.
412 Precondition Failed
The precondition given in one or more of the request-header fields evaluated to false when it was tested on the server. This response code allows the client to place preconditions on the current resource metainformation (header field data) and thus prevent the requested method from being applied to a resource other than the one intended.
413 Request Entity Too Large
The server is refusing to process a request because the request entity is larger than the server is willing or able to process. The server may close the connection to prevent the client from continuing the request.
414 Request-URI Too Long
The server is refusing to service the request because the Request-URI is longer than the server is willing to interpret.
415 Unsupported Media Type
The server is refusing to service the request because the entity of the request is in a format not supported by the requested resource for the requested method.
Internal Error 500
The server encountered an unexpected condition which prevented it from fulfilling the request. Your request could not be processed due to an internal server error.
Not implemented 501
The server does not support the functionality required to fulfill the request. This is the appropriate response when the server does not recognize the request method and is not capable of supporting it for any resource.
502 Bad Gateway
The server, while acting as a gateway or proxy, received an invalid response from the upstream server it accessed in attempting to fulfill the request.
503 Service Unavailable
The server is currently unable to handle the request due to a temporary overloading or maintenance of the server. The implication is that this is a temporary condition which will be alleviated after some delay. If known, the length of the delay may be indicated in a Retry-After header. If no Retry-After is given, you should handle the response as it would for a 500 response.
504 Gateway Timeout
The server, while acting as a gateway or proxy, did not receive a timely response from the upstream server it accessed in attempting to complete the request.
505 HTTP Version Not Supported
The server does not support, or refuses to support, the HTTP protocol version that was used in the request message. The response should contain an entity describing why that version is not supported and what other protocols are supported by that server.

Magic Cards Puzzle

Amongst the many card tricks this puzzle is also a magic trick that require a previously devised logic. As usual you have to tell about a card that you haven't seen. Lets look over the riddle here:

Your friend(B) tells a third person(C) to pick any 5 cards out of the deck of 52 cards without any jokers. That person can inspect, shuffle your cards i.e. the cards are genuine and have no markings.
Now starts the fun part. He(C) picked the 5 cards and handed over to your friend(B). B looked at the cards and picked 1 card out of them and returned back to C without showing it to anyone else. Afterwards B rearranged the remaining four cards in a special way, and gave those cards to you.
You looked at the card and told C what card was returned back to C

You have to devise such a strategy that is known to B (your friend) and that special way that will eventually tell you correctly, what was the card returned to C (the third person)

Solution to The Doors Puzzle

Havent tried it yet. Play here The Doors Puzzle

The solution to one of the closed room puzzle "The Doors" where you are locked amongst many rooms in a house. Walk through the doors and find the way out. Find and use different items to get rid of the haunting interlocked rooms. Here is the solution categorized on the basis of rooms

The game starts from the main hall and you can find the following items
- red card is in the bottom drawer of the chest
- letter piece can be seen stuck in the floorboards when you face the picture
- piece of the cube is on the side of the radiator -- it looks like a tetris piece
- also, note that if you click on the portrait, there is a safe behind it.

Living Room
- letter piece is in the pocket of the coat (lift the sleeve)
- cube piece on the radiator in this room too
- cube piece next to the phone
- cube piece in the fireplace
- purple card under the couch cushions (when facing the couch at an angle)

Drag the newly-formed cube into the holder by the door (the one that's in the same corner
as the coat) and you will reach the office

The Office:
- another letter piece is on the floor behind the chair
- a hospital intake sheet is in the bottom drawer of the file cabinet - note the time
the patient was admitted
- the blue card is stuck inside a large pink book with heavier outlines
- the gray card is underneath the lamp in the corner
- drag the hour hand back to the time you noted on the medical form, and you've
got your key to the bedroom

The Bedroom: (the room is upside down)
- pick up the picture and look very closely at the code on the bottom of it (SCAPE).
match that up with a telephone keypad and enter the resulting numbers into the safe.
- go back to the bedroom and get the card from under the pillow and the letter piece
from inside the nightstand
- the cube from the safe goes under the Almira, and you enter kitchen.

The Kitchen:
- the last card is on the empty shelves to your right
- If you close the open pantry door and click on the shelves behind it, you will find the
last cube, disassembled.

Each symbol (on the doors and the cards) corresponds to a single room. Go back and take
notes of what rooms you end up in when you pass through a door with a symbol, and then
just arrange the cards in the order you were able to access the rooms. Now thats a workout.

Here is the solution for it too
0 - blue, 1 - green, 2 - orange, 3 - red, 4 - purple, 5 - gray
Do it again slide the cube and you are out!!!

Know the color or die puzzle

The puzzle calls for a planning for life :D.

A medieval age mad king devices another mad trick for his fun that plays on life of his best 100 men.

He calls them and line them up and then places a red or a white cap on everyone's head. After lining up they are not allowed to communicate among themselves and can only look at all the men in front of them , not himself and not behind the person himself.

He then tells them to that he will start from the end of the line and ask the person the color of the cap he is wearing (from the person in the line from whom the question is asked) . If he is correct he survives and stays there, and if incorrect he dies silently and the other in front of him wont even know about it. He will keep on moving until he reaches the first person in line.
Any break in rule or devising a way to communicate among themselves calls for killing of all of them.

Now, what is the maximum number of men that can survive for sure? Whats the plan?

It is made by a batch mate of mine, Himschwet Gaurav at IIT Delhi with himself in the lead. Filmed at one of the room in the hostels and with nothing fancy in place. And please don't be disappointed on "not using a beedi" and some other "Bipasha Basu".
It will sure be liked by all of you. IIT Delhites sure hit hard and we rock.
The song was originally filmed on Bipasha Basu and Saif Ali Khan.
There are more to come.. Play the song and enjoy. Please do comment on it!!!!

F1 from Inside... the ultimate experience

'F1' is not only just 'F1'
F1 car is made up of 80,000 components, if it were assembled 99.9% correctly, it would still start the race with 80 things wrong!
When an F1 driver hits the brakes on his car he experiences retardation or deceleration comparable to a regular car driving through a BRICK wall at 300kmph!!!
F1 car can go from 0 to 160 kph AND back to 0 in FOUR seconds!!!!!!!
F1 car engines last only for about 2 hours of racing mostly before blowing up on the other hand we expect our engines to last us for a decent 20yrs on an average and they quite faithfully DO....that's the extent to which the engines r pushed to perform... An average F1 driver looses about 4kgs of weight after just one race due to the prolonged exposure to high G forces and temperatures for little over an hour (Yeah that's right!!!) At 550kg a F1 car is less than half the weight of a Mini.

To give you an idea of just how important aerodynamic design and added down force can be, small planes can take off at slower speeds than F1 cars travel on the track.
Without aerodynamic down force, high-performance racing cars have sufficient power to produce wheel spin and loss of control at 160 kph. They usually race at over 300 kph. In a street course race like the Monaco grand prix, the down force provides enough suction to lift manhole covers. Before the race all of the manhole covers on the streets have to be welded down to prevent this from happening!
The refuelers used in F1 can supply 12 liters of fuel per second. This means it would take just 4 seconds to fill the tank of an average 50 liter family car. They use the same refueling rigs used on US military helicopters today.
TOP F1 pit crews can refuel and change tyres in around 3 seconds. It took me 8 sec to read above point During the race the tyres lose weight! Each tyre loses about 0.5 kg in weight due to wear. Normal tyres last 60 000 - 100 000 km. Racing tyres are designed to last 90 - 120 km.

A dry-weather F1 tyre reaches peak operating performance (best grip) when tread temperature is between 900C and 1200C.(Water boils boils at 100C remember) At top speed, F1 tyres rotate 50 times a second.
