Overall I believe it has to do with the economic of scales, research, and cost of production. These engines aren't naturally aspirated now. The drive train consist also of an electrical KERS systems and a complicated turbo system(s) to generate the incredible power for the 1.6 Liter V8's. The...

It's been years since I took a nuerophyschology (or was it neuroscience) course but I distinctly remember it's relative to the individual and his/her state of mind and many other variables. Can it be quantified? Possibly to some degree but the perception of pain is a very complex phenomenon. For...

Currently I'm running 14-18 miles a week anywhere from a 6-8 mile/hour pace. I do weightlifting 5-6 times a week in 1 hour sessions. The weightlifting includes bodybuilding, power lifting(new to me, but it was a 55 year old man that taught me with the correct form it's quite safe), CrossFit, and...

Acura RSX-S with close to 200,000 miles. However, this isn't a regular 200,000 miles of use. It's me driving this car to it's 8100 rpm redline under brutal acceleration. Downshifting the car under hard conditions. This little car is a pocket rocket. Not one single problem. Most cars driven in...

Be careful. I do a lot of personal trainer. There are a lot of tradeoffs with each diet, and there is a lot of misinformation. Honestly, I always tell everyone to learn the basics of the chemistry behind metabolism. Nothing fancy (3 hours of research). Understand why your body is a big glucose...

I'm currently teaching at a community college full-time due to horrific 3 month post doc tenure. A masters is the minimum. However, I would say at least half of the full time faculty hold doctorates in the science department. Some of the full time employees actually publish (via other...

Graph theory is heavily applied in theoretical chemistry and chemical physics (matter of fact, there are a number of books that specialize on the matter). Especially to applications entailing organic compounds with extensive covalent bond networks (ie many aliphatic organic compounds and...

I didn't care too much for Robin Williams until the last 7-8 years. However, when I saw Christopher Nolan's Insomnia I realized his acting ability in non comical roles. His portrayal of hardened and evil writer isn't easy to pull off but it was more than believable. He again blow me away in Good...

We offer this course in our department. Typically, like it's already been stated, it's a course that covers selected topics over the normal two semesters of chemistry that are usually more oriented towards engineering disciplines in one course. However, in our school, there's a exception for...

To the OP: like someone has already stated, the concept of free speech is at a public environment. While I don't agree with everything at physicsforums.com, the servers and website is a private domain. This website doesn't charge you for anything and provides a domain for learning and civil...

Thank you. When Borek asked the question I wasn't sure. I attempted to look it up and the answer was not straightforward. Do you have any links or papers you can link on oceanic CO2 emission/sinks?

It may help to incorporate that oceans are large CO2 emitters.

If you want an entry level introduction, I would suggest Asmar's Partial Differential Equations (it's the book we used for the PDE course I took) and a PDF of the solutions is offered. It briefly introduces the basics of differential equations and assumes little knowledge of DE. It introduces...

There will always be fossil fuels. There will be a point were the cost to extract fossil fuels will exceed some economic and energy cost that will not be viable to extract and process the fuel.

Audi a few years back raced released the R18 & R15 at Le Mans in prototype racing division. They were diesel powered and had exceptional acceleration and top end high speed. However, like it was mentioned above, the engines, specifications, and overall aerodynamics were made for high end...
