Am I the only one happy about machines taking jobs? Manual labor jobs are the easiest for machines to perform, and are usually done by uneducated people because they don't require much intellectual skill. If machines made human role obsolete, it would have some drawbacks of course like blue collar unemployment, but I think the benefits outweigh the costs in this.

Since the only jobs left are jobs that require human intellect, more people are white collar. This makes education all the more important to society, giving incentive for more and better schools. Also, things...

There wouldn't be more doctors because they only let a fixed number of students to become doctors. If there were an increase in the number of doctors then their wages would go down and they don't want that. (also the quality/skill of doctors would go down)

The other jobs you mentioned are already highly saturated, more students there wouldn't mean they'd have jobs (and if they did then the wages would again go down).

If you can catch it and stick it in the freezer for about 5 minutes it will be incredibly slow once you take it out. Up to 10 minutes and you can handle it (though it will quickly regain mobility).

gravity

Yeah, but then how are rockets, satellites, etc able to escape Earth's gravity? Of course they have added thrust but isn't the whole idea that gravity gradually diminishes the higher up, or the further into the atmosphere, you go? At the outer limits of the atmosphere there should be very little gravity holding it to the Earth. At some point, shouldn't the vacuum of space outweigh the effects of gravity on some portion of the outer atmosphere?

BOINC and distributed computing in general is amazing, and there are so many other interesting projects... is it worth it to use the computing time for the search of radio signals from other civilizations?

You can't. Even if you had the money and an Phd in aerospace it would be really hard without NASA, Russian or help of other space agencies. This is because the metallurgy used in rockets is a closely guarded secret. It's why only a handful of nations have a space program.

Hey /sci/, I'm really interested in the branching patterns of plants and I have a weird question.

Has any research ever been done on the topic of how branching patterns are "coded" for in plant genetics. There's so many interesting patterns and I would really like to read more on how the plants "know" to grow branches like this.

I mean, obviously it's to maximize sunlight for the leaves and have flowers in advantageous positions but what makes an oak grow branches in a different pattern than a pine tree?

I really want to...
>>
That's a good question Anon.
There are many examples of things like this in nature that really should be looked into.
On a similar note I've always wondered how the brain is initially formatted - i.e. turns from a bundle of new cells into one of the most highly specialised computers in existance?
>>
>>8231680
Yeah I think that question is in the same vein. Like what genetic/hormonal mechanism tells a plant cell it should start diving in a different direction to form a branch or what mechanism tells a neuron that it should be concerned with a certain type of stimulus.

I've always been reallt interested in how plants seem to mimic fractals. Like if you look at how the first branches come off of a stem and then look at how sub branches come off of other branches it's obviously the same pattern being repeated.

I'd...
>>
>>8231693
Ah well general growth patterns like that are mainly to maximise light-gathering potential for the smallest amount of growth, that boils down to mathematics.
Methinks plants behave a bit like a cellular automaton, cells will grow in certain directions based on some in-built rules. The patterns formed in their growth will be a result of these rules.
