From what I understand the mainstream science does not consider the AAT to be valid mostly because of lack of evidence. But has the AAT been disproved? I mean it seems to be quite easy. For example:
The theory requires our ancestors to be...
Hello,
I'm having problem understanding the output of the integrating op amp.

Thanks for all the answers!
Interesting, so what you're saying is that it's possible that our brain size is just a byproduct of some other mutations, and wasn't originally a feature selected for? Somehow I thought that the gradual rise in size of a brain demands some justification in...
Ok, I'm not a biologist, but here's my take on it.
I don't think you can actually infer evolution in any direction from such an insignificant period of time. We use pharmaceuticals for maybe 200 years? That's nothing in evolutionary terms, and the phenomenon itself will be (I think) very short...
Hello,
I was interested in human consciousness, and I picked up Daniel Dennett's book "Consciousness Explained" and something he claims there got me thinking:
He says that human brain evolved from chimp-size to homo-sapiens-size in a period after humans learned to stand on 2 feet, and before...
If there is a black hole in the center of a galaxy, then it will probably suck the galaxy into it eventually, but I don't know if every galaxy has to have black hole in its center, or if it's not possible for a body to have stable orbit around such black hole.
Dark matter and dark energy are...
Heh, I really know what timescales are involved, I have recently read two books on evolution. But it is not the only force at work. Evolutionary changes in 1000 years will be minuscule, sure, but I was talking about artificial changes dictated by cultural changes, which (compared to evolution)...
I realize that, but think about genetic engineering. In a hundred years or so you will probably be able to choose hair, eye and skin color of your child (or even yourself). And the standard for beauty changes very quickly, think what was considered beautiful 50 and 300 years ago. I think in a...
Exactly. If we somehow manage not to destroy ourselves, there is no telling how "humans" will look like in a 1000 of years, let alone in millions or billions of years. Even if we went back to stone age tomorrow, and forgot about genetic engineering etc. in two, three million years we would look...
Thanks! So it IS ~583.92/2 evening/morning star (with 8 and 50 days of transition), but I missed that Venus being now far away from the Sun and thus it has already traveled 583.92/4 of it's "evening star time"... had I noticed that I could probably calculate some rough estimation whether Venus...
Venus' synodic period is 583.92 days. Does that mean that Venus is 583.92/2 days the evening star and 583.92/2 days the morning star (with some period in between when it's probably to close to the sun to be visible)? What I want to know is some kind of formula so that I know where and when to...
Today I stumbled upon a cleverly designed levitating lamp and I immediately thought about this topic. You should watch this video:

and the related ones. Maybe it will give you some idea how this kind of thing may be done. As you can see, it doesn't use permanent...
This is a parody of the equally ridiculous replies of the Miss USA contestants about the theory of evolution (link to the original video in the description)

UV is from 10 to 400 nm, so no, you won't get a sunburn trough the glass.
