Gravitational forces dominate the physics of the universe at large scales and EM forces have negligible effect on the course of planets and stars.

How is this possible considering EM forces are 10^36 times stronger than gravity!

It all comes down to one simple fact, EM forces are balanced with counter forces (+ vs -, N vs S) while gravity is a monopolar force. So while EM has a tendency to cancel itself out by attracting its opposite no such effect limits gravity.

My take away: nuance is everything to the big picture in any problem

@penny

the point is "first past the post" voting has been the only form of voting we have had since the begining of america. despite this we have had 8 different parties win presidential election and even in recent history just a few decades ago we have a thid party come **very** close to winning.

I'm not claiming a third party vote is likely by any means. but it is certainly possible with the current system of voting, should the proper mentality arise in the people.

@vnarek

For the sake of clarity I want to make a few corrections...

I compiled the list rather hastily and made a few mistakes

1) there are a few non-US cases in here, most are US though

2) some of these cases arent the result of police killings directly but also include police injustice such as murders that were not investigated by police.

I will have to do a revised list that is a bit more accurate when i have time to fact check this one by one.

Most of them are fairly accurate though.

Is a dogmatologist a person who studies dogma, or someone who studies diseases that effect the skin of dogs?

hmmmmmm.....

In wake of the death of George Floyd at the hands of police, an unjust murder by people hungry with power I just want to remind everyone this isnt the exception in the USA, it is the norm.

Each year we have dozens of innocent or non-violent criminals murdered by police with plenty of evidence and the police almost always get off with little or no punishment, certainly arent treated as the murderers they are. Here is an incomplete list of many of the people unjustly murdered by police in the USA with evidence to back it up and with no or little justice ever served:

Clarke's Three laws (#2 is my favorite):

1. When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.

2. The only way of discovering the limits of the possible is to venture a little way past them into the impossible.

3. Any sufficiently advanced technology is indistinguishable from magic.

Aaaaannnddd another person murdered in the good ol' USA for a nonviolent crime.

Here's a daily, routine event, from our @users report today... 😛

, we are going

Welcome, but answer the Questions, or... [ Depicted? daily purge of new accounts in the morning; not accepted gets thumbs down ]

A part of me is a bit pleased to see scholar.social slowly dying.They block a huge portion of the fediverse without justification while simultaneously accusing other instances of wrong doing without bothering to back up those claims with evidence or even links to posts, they certainly dont give moderators a chance to address issues, if issues even really existed.

At first a long time ago they silenced us along with half the known Fediverse. I very politely approached the owner and asked if there had been an issue and if there was anything I could to to remedy the situation (I had asked from an alt account). He was furious I dared contact him at all, immediately blocked the account and went on ranting about us being fascists or some nonsense without a single example.

Anyway at the time and over the following months a huge portion of scholar.social users started following us and circumventing the silence and hundreds of accounts started migrating over to . Of course this enraged the owner even more and again with no real reason he changed the silence on QOTO to an outright suspension.

To this day we still see new users all the time closing out their accounts at scholar.social entirely and moving here even though they cant migrate accounts the mastodon way, and active user count on scholar.social has plummeted and their local feeds quality has seriously taken a hit. QOTO has a much larger active users count and a much healthier community I can be proud of. No regrets.

"[Computer science] is not really about computers -- and it's not about computers in the same sense that physics is not really about particle accelerators, and biology is not about microscopes and Petri dishes...and geometry isn't really about using surveying instruments. Now the reason that we think computer science is about computers is pretty much the same reason that the Egyptians thought geometry was about surveying instruments: when some field is just getting started and you don't really understand it very well, it's very easy to confuse the essence of what you're doing with the tools that you use." - Hal Ableson (author of SICP).

SICP will show you how CS people 'think' about programming problems and teach you your first language (a semi-toy language, useful for instruction) so it's a great first book. I haven't read the Concrete Math book so I can't really comment on it but I'd definitely encourage you to seek out a good algorithms course after that. I think Harvard has some free courses online. Then you'll want to learn a very high level language like Python for general applications. After that, what tools you learn will be more specific to what you want to end up doing.

@MutoShack @freemo @nyetoots

I started out in Zoology and then moved into a MS in CS later in my career. The advice @freemo is giving is solid. Anyone with a decent logical mind can do well at the practice of programming (writing good code, working with other developers, etc) but you'll be limited on the design side without brushing up on your math. If you've made it through Cal2 then you should have a strong enough grounding to pick most of the other stuff up. Discrete math and Linear Algebre would be good courses to look for online as supplements.

SCIP is a very good intro book but TAoCS is extremely dense and you'll most likely miss most of the nuance without the equivalent of an intro to algorithms course.

@hansw@mastodon.social THC is THC, and CBD is CBD, they are no different from one strain to the next.

The reason different strains give different effects is because of the ratio of the canibinoids, specifically the ratio of CBD to THC which is the vast majority of what determines effect.

"head highs" as they are called are plants high in THC and low in CBD, sometimes as low as 0.1%. Body highs or mellow highs (where you want to fall asleep) would be the result of a high CBD content along side a decent amount of THC, a 1:1 ratio of each would give an effect that would make you feel tired and relaxed without much of a head high at all.

CBD only has a psychological effect when along side THC though. While CBD's psychoactive effect is very significant along side THC it has almost no psychoactive properties when on its own. The reason for this is how it acts on the receptors in your brain. THC by itself is whats called an Agonist for CB1 and CB2 receptors. By itself it will equally bind and "activate" these two receptors, thus causing the head high. On the other hand CBD is what is called a Antagonist of CB1 and CB2 receptors, though has a more significant effect on CB1 than it does on CB2, what this means is it **blocks** the effect of THC such that the THC has less of an effect and the diminished effect is more pronounced with its binding on CB1 than on CB2, this means when CBD is present along side THC not only is the overall effect significantly diminished but the binding of THC to the receptors is no longer balanced between CB1 and CB2 and almost all the activation occurs on the CB2 receptors. This is why CBD will alter the effects of THC but not have any effects on its own.

All that said it means when you have an isolation of nearly pure THC with no CBD present not only will you get a head high, but the severity of the high will be significant (so usually a good idea to do a much lower dose.
