/sci/, do photons change what colour something is?

I mean... tree's could actually be purple for all we know

I can't tell if these kinds of things are trolls anymore....

Can anyone suggest some other Scientifically minded forums?

Hey /sci/, how do you wind down from all of that thinking?
I'm getting tons of headaches and I'm having trouble sleeping

What's the difference between a proton and an electron?

All alternative forms of energy are so dependent on the very petroleum that they are intended to replace that the use of them is largely self-defeating and irrational. Alternative sources ultimately don’t have enough “bang” to replace 30 billion annual barrels of oil — or even to replace more than the tiniest fraction of that amount.
Petroleum is required to extract, process, and transport almost any other form of energy; a coal mine is not operated by coal-powered equipment. It takes “oil energy” to make “alternative energy.”
The use of unconventional oil (shale deposits, tar sands, heavy oil) poses several problems besides that of net energy. Large quantities of conventional oil are needed to process the oil from these unconventional sources, so net energy recovery is low. The pollution problems are considerable, and it is not certain how much environmental damage the human race is willing to endure. Even if these problems could be solved, the human population will continue to increase, and developing nations will be trying to industrialize. With unconventional oil we are, quite literally, scraping the bottom of the barrel.

A "point" is a primitive notion. It's an undefined concept upon which other concepts are defined, like an axiom in logic.

Tahoe, Humboldt, Chico, Fort Bragg, Mendocino, all very cool places.
