What is the coldest temperature in the universe?
.0000000001k
what happened on June 5, 1995
A Bose-Einstein condensate was made
What is a quantum computer?
A computer made up of atoms A computer that makes use of the quantum states of subatomic particles to store information.
What makes the bowl used for evaporative cooling?
A magnetic feild
What is the name of the temperature -273 Degrees C?
Absolute Zero
What is the central idea behind quantum mechanics?
Atoms are particles
What is the viscosity of a superfluid
Zero viscosity
Who won the assault to "Mt Hydrogen"
Dewar
Who were the scientists involved in the quest to conquer "Mt. Hydrogen"?
Dewar and Heike
What did Cornell forget to do in Stockholm?
Forgot to bow to the king
Who successfully explained superconductivity?
Heike
who had won the race to liquefy helium?
Heike
what tool did Cornell and Wieman use to cool the metallic atoms?
Lasers (slow down and become cold)
What is a Bose-Einstein condensate?
New form/state of matter; matter can exist at various states; A Bose-Einstein condensate (BEC) is a state of matter of a dilute gas of bosons cooled to temperatures very close to absolute zero (that is, very near 0 K or −273.15 °C). Under such conditions, a large fraction of bosons occupy the lowest quantum state, at which point macroscopic quantum phenomena become apparent.
What was the prize for winning the race to liquefy helium?
Nobel Prize
What did Faraday call the gasses that couldn't be liquefied by pressure?
Permanent gasses
Where is the coldest place on earth?
South Pole
What happened to the ball in liquid oxygen?
The ball turned hard and broke when hit by the hammer
What did Carl Wieman get from the fax machine?
The chip that makes the laser
How did Van der Waals propose to liquefy these gasses?
To cool the gasses
What did Lene Hau want to do with a Bose-Einstein Condensate?
Use condensate to slow down the speed of light
What processes was used to achieve lower and lower temperatures toward -273 Degrees C?
Using Dewars flask and liquid gasses like oxygen
