Hmm...laminates. You could take a PhD in that topic and still not know everything, the field is that vast. When people talk about strength, there are usually 3 primary types of 'strengths' they could be referring to - yield strength, Elastic modulus and toughness. One definition of the YS...

*Starts taking notes* :smile: How about Feynman? From what I was told by some that he is good, but at times tends to dwell too much on superfluous points. Otherwise I still have the textbooks from my A-levels (with lots of unread chapters on QM & Relativity...), like Young and Hecht...

I decided to expand my knowledge on Physics a little from what I was taught at school, which was mostly classical/Newtonian stuff. I am planning on learning both Quantum Mechanics & Relativity. Which one should I learn first, so that the knowledge from that first subject would help me learn the...

Obviously, anyone with osteoporosis can tell you that bones can be too soft. But can bones be too hard? I thought that this may be possible because part of cushioning we get when we do everything from walking to jumping, comes from the flexing/compressing of bones (however small). The rest...

Okay...my biology knowledge is very rusty, but aren't both the nerve impulse and the muscle composition the factors here? So the nerve impulse to lift a 5kg mass is less than the nerve impulse to life a 10kg one. Or for the same nerve impulse strength, a larger muscle will have an easier time...

Can any biology-savvy people comment on the viability of implants which boost the nervous signals to muscles, effectively making someone superhuman in strength and endurance? I can see how someone with these implants may end up killing themselves from over-exertion, but would something like this...

LOL. I was on a flight from Sydney to Adelaide during a holiday to Australia some time ago, and the flight attendant over the PA went something like: "Ladies and gentlemen, welcome aboard the Qantas flight from Sydney to Perth." At which point, everyone started looking around and panicking...

Try "French military victories" instead

You've got to teach me how to do that, mate [zz)] My last job had a 90 min commute to work .

Ask away dude. It is actually quite fun, in a nostalgic way, to get asked the stuff I too, used to pore over (usually a few days before the exams [b(]). Of course, you should know that my exposure to materials science only came through the modules I took in my engineering course, and was not...

Probably because a person lying down takes up more plan area than a person standing up, or seated. As the bottom line is profitability, they want to cram as many sheep (us) as possible into the train to sell the most tickets. I've also nodded off and slept past my station. Not nice. I'd...

Unless you are talking about transgenics which are genetically modified after they are conceived, I don't see how genetic engineering can be a conscious decision for children. Can we unanimously agree that smarter, stronger, fitter and longer-lived is better? If we can, then I don't see why...

I too, think traditional metal blades are better than ceramic ones simply because they are tougher and won't break when you accidentally hit them too hard. There may be a few niche applications where ceramic blades are more popular, but I am not a knife-maniac so I can only speculate. Fooling...

What is your opinion of it? Do you approve of it? I think that there is no law which states that evolution of a species has to be a purely natural process that does not involve the 'artificial' intervention of the own species. If a species were developed and intelligent enough to tinker with...

Tip displacement for a point force on a simple beam varies with the longitudinal distance variable in a cubic manner. For very small z, this can be approximately linear (a z^n \rightarrow 0 argument for n > 1 and z < 1). Still, I think your friends are lying. You are talking very small z...
