It is much easier to learn a subject, be it Physics or Tennis, if you are motivated to learn the subject. To the extent the author sees a variation in the amount of effort devoted to his class, he is observing a variation of motivation. Students who need direct support in order to devote time to...
It would be interesting to review the remediation efforts made at Hiroshima and Nagasaki, now 70 years old, and determine how effective they were, and what impact remediation has had on the million or so people living in those contaminated areas.
The energy of combustion of gas phase methane is available in a reference book - look it up. But you first have to covert the LN2 in the tanks into gas phase methane. That is energy absorbe, and a loss. There are tables with that info, too. The combustion products are gaseous H2O and CO2...
These materials are both transparent in the visible regime of light. However, because they have a higher index of refraction, the light passing through small particles is refracted and reflected off of many surfaces. The resultant scattered light makes them appear white. If the particles are...
If you want to be really wealthy, DO NOT go into law or medicine. Finance? maybe. Start your own business? Doing what? Most successful business that I am directly familiar with were started by an engineer.
There are several factors that determine a starting salary: The degree you choose (ChemE is currently ranked at the top), the school you graduate from, your school record and whether you have any internship experience.
A MS will be paid slightly more than a BS. But consider the fact that you...
That is true. There are other color combinations of light that lead to ambiguity in interpretation. There is also variation on the color response in the eye among human populations (color blindness is an extreme case) that lead to differences in interpretation. A great deal of research has...
Thermal expansion is a macroscopic property and does not need a microscopic interpretation in order to make a calculation. Heating a material will not cause it to break, unless it is constrained, and mechanical stresses are imposed. Even then, analyses using fracture mechanics depend on...
The frequency range near 400 nm is defined as being "violet" . Therefore the color "violet" does exist, by definition. You are confusing this with the problem that the human eye has differentiating between some combinations of color. The eye responds in an identical manner to a two color source...
As somebody who has actually carried out such calculations, using finite element programs (FEA), let me try to explain it to you. The expanding material only expands according to the temperature it is at. But, as you point out, this is not known in a dynamic situation. The surrounding...
No.
The red sensing rods also detect light in the deep blue. A response that is both red and blue is seen as a combination of red and blue. Our eyes cannot differentiate between a mixture of two colors and deep blue. Both look violet.

I saw a microscope installation that explores a dimension not mentioned by Feyman - time A sub-picosec high res TEM can map dynamic processes on an atomic scale

First. with cloud computing, a larger fraction of the total number of processors sold go to big companies. The rest of us use them indirectly - for example, we are told what products we want to buy when we browse a web page :oldsmile:.
However, there is an unmet need for significantly larger...
"I would contend that unless we get something that the common user will need a heavier-duty processor for, we won't see the kinds of technological leaps that we got during the 1970s-1990s."
Meanwhile, software engineers are simultaneously utilizing thousands of computers, sitting on farms at...
