Does anyone has done research into lights biological effects? I've been researching the effects of red light and UV light on testosterone at different levels of exposure, have found somewhat solid evidence for a correlation for UV light and some support of correlation for infrared/near infrared. I'm trying to get my body to produce as much test as possible without actually using gear. I'm looking at grow lights for weed as a possible source of light therapy, there's red led and other full spectrum ones that mimic sunlight. If there's more information about this I'd want to hear

Why aren't photosynthesising animals more common?

>> No.11316873

Because photosynthesis is a shit way of getting energy, you pretty much have to be a stationary creature to get any benefit.
Even the few animals that can photosynthesize that we know of don't rely on it, it's just a handy way to stretch out meals.
The energy an animal needs just to move is huge compared to what a plant expends.

>> No.11316890

Super effective to fire type and flying type animals.

>> No.11316893

But animals get all that energy from photosynthesising plants, directly and indirectly.

Perhaps this is unsuitable for this board... but is there a proper way to get your DNA sequenced without having all of your data being scooped up and sold to various advertising and marketing companies, not to mention healthcare companies? I'm just curious to look at some of my identified genes and look at which ones have good or bad reputation and what they seem to correlate with. I'm interested in that stuff.

As in reverse aging, unlikely, at least for a foreseeable future.
A bit more realistic is developing anti-aging drugs or even DNA modifications that makes us live longer and age less.
Nobody really knows if and when though, tentatively I'd say the former at least 20 years, the latter 100.

It makes you think about the concept of infinite limits. School taught me that something was "approaching" but never touching infinity.
Me thinks people do not understand the term "approach". It infers a constant directional force to something right?
How can something have a constant directional force to something yet avoid meeting it without stopping it's approach towards it?
That definition always bugged me at school because maths geniuses seem ok with it, but linguistically orientated people like me get confused by it because it's a complete oxymoron.

By definition something cannot approach anything to the infinite limit without warping.
But at the same time, I get what they mean as an estimation of that concept. It's just poorly worded.

>> No.11316449

I don't know anything about reading science textbooks, but I have to read a lot of math papers/textbooks, and I think this strategy is pretty useful in other areas as well. I speed read the entire book/paper. Probably about 3-4 pages a minute. By the end of if, I understand very little, but I know an overview of the material contained. Then I reread with that big picture in mind and usually I kinda pick up on the important details. If I need to go really in depth, THEN I'll pay attention to proofs and MAYBE to practice problems. Obviously if you do everything in the book you'll really understand the content, but for a 300 page math textbook, that's gonna be a few hundred hours.

>> No.11316466

that's true OP. learning a textbook itself is not optimal. kinda like asking 'what's the best way to dig a ditch with a spoon?'. Not a good investment of the limited time you have

>I understand that helium is lighter than gravity
Helium balloons are kept aloft by buoyant forces similar to boats. The reason they float is because their weight is less than the buoyant force that acts on them. The weight is a function of density and volume of the object but the buoyant force is a function of the volume of the object and the density of the surrounding fluid. So as long as the object is less dense than the fluid it will float.
