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
