>CO2 in the atmosphere is increasing.
And that's a good thing.

Literally all life on the planet almost ended because most CO2 was trapped in fossils underground and during ice ages even more was trapped in the ice. Plant life needs a minimum of about 150ppm and we came dangerously close to that threshold.
Plant life thrives on much higher levels of CO2 up to about 2000ppm after plants are negatively affected.
Humans can survive up 60000ppm.
During the Cambrian-Ordovician period CO2 was at between 4000 and 6000ppm and yet that was when the first coral reef formations took place. A far cry from the bleaching that's supposedly being caused at 400ppm.

He wasn't a fraudster, he was just retarded. A classic victim of the Dunning-Kruger effect. He would create and train a very simplified Artificial Neural Network that evaluated whether a move was good or bad. Then he would memorize the parameters of the ANN, and on each move he would calculate the entire ANN on his brain to see if a candidate move was good or not. I kid you not:
He convinced himself that he could easily do hundreds of calculations and memorize thousands of practically random numbers, and that he would do all of this quickly enough to not lose on time. He never reached that point though. He got stuck trying to create the artificial neural network that would create the parameters for him to memorize and he gave up.

If you consider neural networks to be "algorithms" (and technically speaking they are) then yes, but this probably isn't what you're asking for.

Should I go back and get a master's in a different field, like math, since I do enjoy the math side of things quite a bit (but I don't deal with it a lot in my practice).

Or should I maybe take some more structural engineering coursework, since structural engineering seems more interesting to me, and they seem to do more of the work that I want to do and with better pay.

Any suggestions?

Well, I guess I was hoping for more desk/analysis work, but it can be a lot of field work. I don't mind field work every once in a while, but I guess I'd just prefer more office work.

If you love field work, it will probably pretty enjoyable for you. If you don't enjoy field work or don't want to do much of it, I would stay away from Geotech and pick another discipline in Civil.

Which is why I was maybe thinking of going the Structural route. Seems more math-heavy and logical, which appeals to me.

>> No.11145678

If you want to argue frequency, you need to keep ind mind that death is not a consequence for most medical transactions. So you would need to account for transactions where this risk realistically exists, but isn't obviously likely.

Quoted By: >>11142723

Adding energy to any material, such as by heating it, almost always makes its structure less orderly. Ice, for example, with its crystalline structure, melts to become liquid water, with no order at all. But in new experiments by physicists at MIT and elsewhere, the opposite happens: When a pattern called a charge density wave in a certain material is hit with a fast laser pulse, a whole new charge density wave is created -- a highly ordered state, instead of the expected disorder. The surprising finding could help to reveal unseen properties in materials of all kinds.

The experiments made use of a material called lanthanum tritelluride, which naturally forms itself into a layered structure. In this material, a wavelike pattern of electrons in high- and low-density regions forms spontaneously but is confined to a single direction within the material. But when hit with an ultrafast burst of laser light -- less than a picosecond long, or under one trillionth of a second -- that pattern, called a charge density wave or CDW, is obliterated, and a new CDW, at right angles to the original, pops into existence. This new, perpendicular CDW is something that has never been observed before in this material. It exists for only a flash, disappearing within a few more picoseconds. As it disappears, the original one comes back into view, suggesting that its presence had been somehow suppressed by the new one.

>> No.11142723

Isn't this seen with all fluids and materials viscous enough to deform? What I mean by this is when you add energy to something it changes shape, based on the frequency of the energy input. As soon as the input stops, the pattern also stops. An example of this can be seen in this music video: https://www.youtube.com/watch?v=Q3oItpVa9fs

Take Bupropion it helped me quit with only a light mental fog during. Quitting always sucks at first but it’ll be worth it

I managed to quit cigs by switching temporarily to chew. Then I tapered my use of chew down to nothing over a few months. I still miss chew sometimes, though.

Suck it up. The trick with quitting is to find something else to substitute behaviors. Stock up on carrot sticks and sunflower seeds it will help you with the oral fixation and give you something to do with your hands. Blast out some pushups or crunches every time you get a bad craving, keep going until it stops.
Eat b and c vitamins like fucking candy for the first few weeks.
The worst part about kicking any addiction isn't that it makes you feel like shit, but that you know how easy it is to make the shitty feeling go away.

why the vitamins like candy?
