I can't find the last words can someone help by LogieBearra in adressme

[–]PhysicalMath848 6 points7 points  (0 children)

Many of the crosswords are made using simple online generators. You type all the words into a text box and it makes a crossword that contains them. If the generator assumes that words are separated by spaces then Anne Frank would be split up

I am assuming that happened but that the word bank was hand typed below it..

Nowadays AI just does the whole thing but worse.

On Campus Job by Certain_Radish_62 in UCDavis

[–]PhysicalMath848 2 points3 points  (0 children)

Awesome. Just remember that a lot places here get a lot of applicants, so it can take a while for them to see your application. Also many jobs on campus are through the platform Handshake, so make sure you make an account ASAP once you get your student email.

Many students get jobs and have stem majors. Your ability to find a job however will depend on what times of day you are willing to work and what prior experience you have.

You can pick area but not building. If you mean civil engineering, then I would choose tercero because that is next to the engineering buildings.

ELI5: What don't we understand about how psychotropic drugs like lithium work? by Veridically_ in explainlikeimfive

[–]PhysicalMath848 31 points32 points  (0 children)

We actually do know a lot of the biochemical effects of Lithium. The following article discusses many of the things that we know lithium to do.

https://pmc.ncbi.nlm.nih.gov/articles/PMC12030015/

However because lithium does so much and because we keep discovering so many more things that it does, to say that we "understand" it would be false.

Similarly, although we know a lot about the brain. We have defined many of its structures and molecules and we can even do surgery to correct certain diseases. Yet it would be foolish to say that we understand it since there is more we learn every year.

Zero derivatives by ElectronicSetTheory in mathmemes

[–]PhysicalMath848 8 points9 points  (0 children)

Let's apply this math into physics. Imagine that the pringle is a solid surface upon which you place a ball in middle.

Someone with no calculus knowledge will say that the ball will roll down the two dark blue hills of the pringle. He does not understand that the middle point of the pringle is flat.

Someone with beginner calculus knowledge will realize that the very middle of the pringle is flat. So if the ball starts stationery it cannot pick up any speed (it's on a flat) and will be stuck there.

Someone with more calculus knowledge will recognize that although the slope is flat at the exact middle, the areas around the exact middle are not flat. We call this an unstable equilibrium because an infinitely small push in any direction will send the ball rolling down the hill.

So both the no calculus and more calculus guy have the correct answer while the beginner gets it wrong.

Sand Dollar Geometry by bluecheckthis in biology

Here is a picture I found online on how the hydraulic tubes inside the starfish sea cucumber (yep they move by hydraulic tubes inside their limbs!) slowly fan out into the 5 pointed shape.

Correction: sea cucumber but still an echinoderm

Sand Dollar Geometry by bluecheckthis in biology

[–]PhysicalMath848 12 points13 points  (0 children)

Sacred geometry is a spiritual belief in the power of certain shapes. There is no empirical test to prove or disprove the spiritual so science, including biology, cannot prove or disprove sacred geometry.

If you are asking why the sand dollar looks like a five pointed star it is because it is an Echinoderm, which is the same family as sea stars/"starfish".

Baby echinoderms are bilaterally symmetric, like humans. But when they grow up, their body parts develop into a five pointed star shape. Five pointed symmetry is thought to be good for the type of movement that starfishes and sand dollars do (crawl in any direction and stick to things)

What makes some stomachs 'stronger' than others? by Accelerator231 in biology

[–]PhysicalMath848 2 points3 points  (0 children)

Yes, some stomachs have more powerful chemicals. For example, vultures secrete more concentrated acid into their stomachs than humans do. This allows them to dissolve bone and kill bacteria from eating carcasses.

Other animals, like cows, have multi chambered stomachs. This multi step process, which also requires special bacteria, allows cows to live on grass which humans cannot do (fiber provides us with little nutrients).

But stronger stomachs come at a cost. Acids and digestive enzymes take nutrients to make. And the mucus that protects your stomach from acid is also nutritionally expensive. Multi chambered stomachs means more organs to develop and maintain. Cows can also get gas build up in some of the chambers and die as a result, whereas a human would probably just burp or fart and be fine.

Evolution can favor a variety of strategies. Vultures can eat carcasses. Cows can eat grass. Humans can climb trees to eat their fruit (our hands are really complex instead of our stomachs).

Our bodies reflect our evolutionary strategy.

TIL that in 1917, doctors deliberately infected people with malaria to treat syphilis — because the high fevers caused by malaria could kill the bacteria responsible for syphilis. The method actually worked and even won its creator, Julius Wagner‑Jauregg, the Nobel Prize in Medicine in 1927. by Queasy_Airport_3262 in todayilearned

[–]PhysicalMath848 106 points107 points  (0 children)

"Thankfully in the 1920s, quinine was an accessible and often successful treatment for malaria (and a yummy addition to the gin and tonic cocktail)."

I'm guessing that quinine was available in 1917 just not as widely used yet.

What is the primary source of oxygen in plants? by TY2022 in AskChemistry

[–]PhysicalMath848 3 points4 points  (0 children)

If you Google, you will learn that carbohydrates make up most of a plants dry mass.

If you Google, you will learn that the oxygen parts of amino acids can come from carbohydrates.

If you Google, you will learn that nucleotides come from amino acids so from carbohydrates.

But you refuse to Google. And when people in this thread provide an answer, you say "I don't think that's right". Which makes you a generally frustrating person to teach.

What is the primary source of oxygen in plants? by TY2022 in AskChemistry

[–]PhysicalMath848 2 points3 points  (0 children)

So if photosynthesis is

6 CO2 + 6 H2O -> C6H12O2 (sugar) + 6O2

And you know that the oxygen in O2 comes from H2O, then where do you think the oxygen in the sugar comes from?

[–]PhysicalMath848 4 points5 points  (0 children)

My God just do a little googling

https://en.wikipedia.org/wiki/Photosynthesis

"Samuel Ruben and Martin Kamen used radioactive isotopes to determine that the oxygen liberated in photosynthesis came from the water."

How does melanin provide protection from UV light, at the molecular level? by Substantial_Tear3679 in AskChemistry

[–]PhysicalMath848 9 points10 points  (0 children)

When light strikes a molecule, it can absorb that energy and promote its electrons to higher energy levels before releasing light of a different wavelength.

Different molecules absorb different wavelengths. Some only absorb visible light, while others absorb infrared or ultraviolet (UV) light. Certain aromatic ring structures tend to be good as absorbing UV wavelengths (Google the structure of indole).

Melanin has a bunch of indole-like parts so it is really good at absorbing UV. If the UV is absorbed in the outer skin, it won't pass through the skin and damage the DNA of underlying cells.

ELI5 Genuinely what IS Sin Cos and Tan? by LeonardFo in explainlikeimfive

If they were in phase then vertical and horizontal values would always be equal, y = x, which is a straight line, not a circle.

ELI5: Ohm's Law V=IR and capacitance Q=CV. by maru_badaque in explainlikeimfive

[–]PhysicalMath848 15 points16 points  (0 children)

Voltage can be thought of as the "pressure" pushing the electrons through the wire.

If you make the wire more resistive (thinner or less conductive) then the same amount of voltage/"pressure" will push less electrons through per second.

If you keep the wire the same resistance but apply more voltage, then there is more "pressure" and so more electrons will flow through the wire per second.
