Going back to your car analogy, is it a bit like doing a 3-D computer design of a car that gives you the knowledge to physically build the thing? Are you trying to mimic that three- dimensional pattern that you've got in your BEC'? Would you then try and actually build a similar pattern, a similar lattice in a solid crystal or something along those lines? Absolutely. The BEC gives me control. All the atoms are the same, and I can create a pattern that is very uniform and has no defect. No defect is very difficult to get in the real world. However, if I have that beautiful control, then I can find out what are the necessary elements in that pattern. Where do l have to put the money to create a better hightemperature superconductor? Do l have to put more effort in having this particular pattern just where the oxygen is in the superconductor? Or do l have to look at where the rare air is? And so on. That is a fantastic tool. In your computer 3-D simulation of the car, are there defects? That's when you can test it. You understand all the laws of aerodynamics, all the laws of physics, and everything is tested in your computer. That is the role that the BEC can have for these other areas. This feature originally appeared on the site for the NOVA program Absolute Zero. Vocabulary Questions: 1. Explain what a Bose-Einstein condensate is in your own words. 2. Define coherence as the term is used in the context of this article. Provide an example from the text of this kind of coherence. 3. In the article BECs are referred to as superuids. What is a superfluid, and how is it different from an ordinary fluid? Text EvidenceIContent Questions: 1. Why do scientists need to cool atoms to such a low temperature to study them? 2. What role does the weak force have in turning hydrogen to helium? 3. How does a BEC give a scientist "control." as the word is used in the last paragraph of the text? Control over what? Explain in detail using information from the text. Writing Prompts: 1. The kinetic molecular theory is based on the idea that all matter is in constant motion. Using information from the text, describe the motion of particles of matter as they transition from the solid state all the way to a Bose-Einstein Condensate. 2. Orozco refers to the laboratory as a \"stadium." Based on the text, what are some of the problems with building larger \"stadiums" for researching BECs? How are the scientists trying to resolve the issues they are facing
