>>6923497 I don't know how it is taught. I went to high school from '90-'94. I know that I got As and Bs until I hit precalc in eleventh grade, where I practically failed. So something went wrong since the first quarter of pre-calc was a glorified review. How did I do so well up to that point if I didn't know the material? Well the story has a happy ending but that definitely points to a problem somewhere earlier in the line. I enjoyed math, and apparently was good at it, except that when the time came I...

>>6915047 no, that's completely fucking retarded, a person in a first world country uses hundreds of trees in his lifetime, planting one more tree means absolutely nothing, the only people who have such luxuries as actual stone tombstones are relatively wealthy people in first world countries and a minority of the world population anyway and the places with actual high populations like africa and india are too fucking poor to plant and grow trees for everyone that dies
the ecological impact would be completely negligible,... Comment too long. Click here to view the full text.
>The possibility that biological material may serve as a medium of extraterrestrial communication is discussed and DNA from bacteriophage phi X174 is investigated to determine whether such a message could be derived from it. It is speculated that advanced civilizations could manipulate viral or bacterial DNA so that its base sequence would carry a coded message in addition to specifying compounds necessary for survival and send a microorganism containing the message to a planet with conditions similar...

Dear /sci/... this is the most fucking amazing short mov I've seen in a while:
>Wanderers is a vision of humanity's expansion into the Solar System, based on scientific ideas and concepts of what our future in space might look like, if it ever happens. The locations depicted in the film are digital recreations of actual places in the Solar System, built from real photos and map data where available. >Without any apparent story, other than what you may fill in by yourself,...

When was the existence of the lipid membrane proven? I know it was initially postulated, based on a belief that polar substances could not enter cells, but this observation was later found to be false.
When was the lipid membrane actually validated? I would expect such a fundamental part of biology to have solid evidence supporting it, but I can't seem to find any.
Then you havent fucking tried very hard. Phospholipid membranes are extremely well studied, and there are even commercial sites that will ship refine products (functionalized proteins and lipids, cholesterols, etc) to your lab for experiments.
There are literally thousands of published articles that deal with this subject.

>>6910115 Yes, they do not help you understand any mathematical concept. I sat down and tried to think about Mathematics and Geometry on LSD. It was a total failure. There was no analytic thought, only emotion.
Actually, yeah. I was reading munkres topology while visiting a friend for shrooms (I couldn't bring my computer; thought I'd bring math texts for the downtime) and tried to read it through the comeup. It got progressively more and more boring until it was absurdly so, and I became furious at the text for being so unenjoyable. Then I noticed that I had been on the same page for about ten minutes, reading the same definition over and over in my head and willing it to make sense. I eventually gave it up and just laid on his bed until the come up was done. While walking... Comment too long. Click here to view the full text.
Any programmers out there with advice on where to find open source projects to work on and/or how to start out as a freelance programmer?
I recently quit my hellish job programming for a major corporation (fixing bugs that have been around for 10+ years, doing all the work that nobody else would touch, etc.), and want to work on projects I'm at least somewhat interested in.
I love programming to the point where it becomes addicting but don't know where to start to build a portfolio and all that. I want to learn more languages but don't think the... Comment too long. Click here to view the full text.

I don't see what the fascination with AI is all about anyway. We just need faster computers. We don't need computers capable of mimicking or replacing us. We don't need to create life, we have too much already.
They need to figure out better ways for humans to fundamentally interact with computers.
How many of you were in the gifted program when you were in elementary-high school?
We had something called GATE here, which I was not a part of. All I can remember is that they got to do arts and crafts after school and they gave a little show at the end of the year.
I was wondering about this because I had a few friends who were at the top of their class when they were younger, and they did pretty well maybe up until the end of high school and even calc 2 was too much for them so they do business or something now.
I was talking to a professor about this... Comment too long. Click here to view the full text.
>>6906401 Ours was called STRETCH (Supplementary Teaching Resources for Educationally Talented CHildren, quite the mouthful).
I wouldn't say it was a perfect predictor of success in the future, but nobody I know who was in the program is doing stupid stuff right now. They are all at least employed, in education, or doing something else positive.
>The Fermi paradox (or Fermi's paradox) is the apparent contradiction between high estimates of the probability of the existence of extraterrestrial civilization and humanity's lack of contact with, or evidence for, such civilizations. The basic points of the argument, made by physicists Enrico Fermi and Michael H. Hart, are:
>The Sun is a typical star, and relatively young. There are billions of stars in the galaxy that are billions of years older. Almost surely, some of these stars will have Earth-like planets. Assuming the Earth is typical, some of these planets may develop intelligent life. Some of these civilizations may develop interstellar travel, a technology Earth is investigating even now (such as the 100 Year Starship). Even at the slow pace of currently envisioned interstellar travel, the galaxy can be completely colonized in a few tens of millions of years. According to this line of thinking, the Earth should already have been colonized, or at least visited. But no convincing evidence of this exists. Furthermore, no confirmed signs of intelligence (see Empirical resolution attempts) elsewhere have yet been spotted in our galaxy or (to the extent it would be detectable) elsewhere in the observable universe. Hence Fermi's question, "Where is everybody?"
I think we vastly overestimate the probability of the evolution if human level *intelligent* life. We only have Earth's life for data, but we also have about 4 billion years of that data. I think intelligent life is extremely rare for the following reasons:
- Unintelligent life is usually more successful than intelligent life. In terms of biomass, plants, single celled organisms, and arthropods are a huge portion of Earth's life. They are extremely stupid creatures, but they dominate the biosphere.... Comment too long. Click here to view the full text.
