The sunlight shining bright and vividly into my room. And i don't like it. THEN with sundown, there is 1 hour maximum this ambiance of sundown and it is incredibly nice.
HOW Can I create or be present where there is that ambiance of the sundown, for all of my afternoon? Instead of the sun shining so annoyingly bright.

Yes, but what is best is

My strategy is to take notes, then I explain what I learned out loud. A few days later, without looking at my notes, again I explain the concepts to myself without refering to my notes, and if I find myself unable to explain something, then I look back at my notes. Do this at regular intervals and it will stick.

Imagine you have an infinite sheet of neutral charge in the (x,y) plane, spanning all of (x,y).
Place a positive charge at the position z = a.
This positive charge induces a negative charge on the sheet, everywhere in the (x,y) plane.
This gives rise to two scenarios, neither of which makes sense.
>1. The sheet originally had an equal amount of positive and negative charges, hence being neutral
If the sheet is now negatively charged everywhere, where the fuck did the positive charges go?
>2. The sheet was originally neutral because it had no positive or negative charges anywhere
So where the fuck did the negative charges come from?

This is a classic problem and there is a crucial detail that needs to be specified. Is the plate grounded? If yes, then the charge gets dissipated. If not, then you will have some characteristic radius where the surface charge density is zero, and it's positive inside and negative outside.

>> No.12793431

>>12793385
Yeah I get what you're saying. It's interesting as a 'frictionless' physics problem. Totally analogous to introducing a grain of sand to an (x,y) plane of particles that are not experiencing any gravitation force. When the massive test point appears, a force vector appears on every point in the plane.

But inducing an electric field on the plane doesn't change the net charge of the plane, so the positive charges must go somewhere (there are at distance = infinite from the origin?) Maybe I'm making an error by thinking of this plane of being bounded though ....


Run it by me again with the gravity analogy. It's the same. Just a vector field.

I am a little confused by this. When you build up a charge on a sheet I thought it would build up the opposing charge on the other side of the sheet. Are there actually charge gradients? That doesn't make sense to me, but thermal gradients don't either.

Yes, charge density is assumed to be continuous. This is a fine assumption on macroscales. You can see (volume) charge density in Maxwell's equations as rho for instance, and there is an analogous quantity for currents. The math is actually much neater with these than with discrete charges.

as of 5 march about only half the Israelian population has recieved the first vaccine dose, 3.9 million individuals have recieved the second dose (39% of the population).

The first point of your argument is then false and the whole argument is pointless.

A 90 year old man died without any warning from the COVID-19 vaccine. Why aren't COVID-19 shots safe for old people?

Go ahead, tell me how I'm wrong. If you can provide ample evidence that SAEs in vaccines are significantly lower than 0.01%, I'll feel safe enough to get the vaccine. And I mean that. My entire premise for not getting the vaccine is that it's safer for me to catch covid19. My decision to get the vaccine is entirely selfish, so I don't give a fuck about this retarded herd immunity argument.

No, science is wrong about things.

For example, scientists claim that one can look at things that are close to you and very tiny by looking at them through a tube with pieces of glass at the end, but also at things that are large and far away. Does that make any sense to you?

Scientists also claim that NASA landed on the moon. If we landed on the moon, why didn't the nasa astronauts see our lady standing there?

Another thing scientists are wrong about is how many genders and sexes there are in the species Homo sapiens. Hint: the answer is 2 (also written 1.999...)

"Scientists" also claim that drunk driving is dangerous. Does that sound right to you?

https://www.reuters.com/article/us-health-coronavirus-japan-supercompute/japan-supercomputer-shows-doubling-masks-offers-little-help-preventing-viral-spread-idUSKBN2AX0BA

>TOKYO - Japanese supercomputer simulations showed that wearing two masks gave limited benefit in blocking viral spread compared with one properly fitted mask.

The findings in part contradict recent recommendations from the U.S. Centers of Disease Control and Prevention (CDC) that two masks were better than one at reducing a person’s exposure to the coronavirus.

Researchers used the Fugaku supercomputer to model the flow of virus particles from people wearing different types and combinations of masks, according to a study released on Thursday by research giant Riken and Kobe University.

Using a single surgical-type mask, made of non-woven material, had 85% effectiveness in blocking particles when worn tightly around the nose and face. Adding a polyurethane mask on top boosted the effectiveness to just 89%.

Wearing two non-woven masks isn’t useful because air resistance builds up and causes leakage around the edges.

>“The performance of double masking simply does not add up,” wrote the researchers, led by Makoto Tsubokura.

In general, professional grade N95 masks were the best in protecting against infection, followed by non-woven masks, cloth masks, and finally polyurethane types, the study showed.
