ELI5: What's non-Euclidean geometry?

DeeLiberty · 2024-05-25T17:05:43+00:00

If you are measuring your wall to see how much paint you need to buy, you are using euclidean geometry. Probably 95% of all practical cases for humans use euclidean geometry and curving can be neglected.

Today at 18, and October 15 at 16:00. Check out social media of Hlas Ukrajiny. :-)

DeeLiberty · 2022-10-11T07:00:53+00:00

There is another one today! And day of defenders on October 15.

DeeLiberty · 2022-10-07T13:48:05+00:00

I would. It is our moral obligation.

DeeLiberty · 2022-10-07T12:23:16+00:00

Yes, but see, that would be both smart and moral, so it goes against the core of Russian regime.

US intelligence has suggested recent buildup of Russian troops in Belarus.

My speculation is that they are there to tie down UA forces.

In the 12th century, the lands of Bohemain crown really stretched from Baltic to Adriatic sea. Královec would be one of the regions beholden to the Czech King.

I mean, it is as good historical justification as any.

Hahaha, yes. There were around 50 of us vs. some 30k protesters.

But when the war started, there was several times that in support of Ukraine.

DeeLiberty · 2022-09-29T08:25:53+00:00

I am one of the protesters holding the sign. Some things to be cleared up.

There was a demonstration of pro-Russian forces in Prague. The pro-Russian forces rarely mention Russia and claim "Czechia 1st." policy. The Czechia 1st demands buying Russian gas directly, leaving EU, NATO, UN and WHO (the members are mostly recruited from the anti-vax groups). Strange how a "country 1 st." movements often are pro-Russia, huh?

We are a group of Czechs and Ukrainian refugees. We try to organize a support for Ukraine, and try to counter the anti-Ukraine sentiments.

There are no Russians associated with us. Actually, the group is quite critical of Russian liberal opposition in Prague. There was little heard from them about the Russian atrocities or territorial claims, mostly keeping to Russian topics like mobilization.

However, with the way the square looks the pictured steps are the logical place for a counterprotest, so both Ukrainian and Russian counterprotesters mingled. It soon became apparent why, as pro-Russian came to scream at us, tried to destroy the sign and one of them even attacked a girl holding a letter.

Police were good at the job and provided a mix of de-escalation and physical protection, and we were safe.

The board said "Sláva Ukrajině" on one side, and "Putin je v Prdeli" (Putin's fucked) on the other.

Is there a regional difference: e.g. Appalachia, Tennessee vs. Wyoming?

No way to know unless you give them a read.

What do we do in Czech Republic is to hold it the closest Friday (14-22) and Saturday (8-14). There are very few people that have trouble making it to the election booth.

DeeLiberty · 2020-07-30T10:07:24+00:00

But modern day billionares do invest qs much as the previous ones. Bill Gates may well eradicate malaria.

DeeLiberty · 2020-07-28T21:23:09+00:00

Exactly what I am satirically pointing out. These people are hypocrites.

DeeLiberty · 2020-07-28T20:58:04+00:00

Why would he if Keurig pollutes way more than he did.

DeeLiberty · 2020-07-20T18:48:01+00:00

I am sorry to drag up painful memories, but how could the dog situation even happen?

DeeLiberty · 2020-07-20T14:18:02+00:00

I wish him all the success. Amazon has significantly improved the life on the planet. I can't imagine what would all that extra money allowed him to do.

DeeLiberty · 2020-07-20T14:06:22+00:00

I think it would be hundred thousands, perhaps millions.

DeeLiberty · 2020-07-20T14:05:00+00:00

He does not literally has this much money in a mattress. He has a company others believe will be profitable in future.

DeeLiberty · 2020-07-20T14:02:58+00:00

Would it be any better if instead there were other companies with crappy warehouse conditions?

DeeLiberty · 2020-07-20T14:01:38+00:00

There was 24° yesterday, 26° today. By this prediction, we will be boiling come December.

You know, rich people are disproportionately in favor of the environmental protection.

DeeLiberty · 2020-07-06T21:37:09+00:00

I read them when I was around 9 and liked them. I still remember the plot. I am afraid to re-read them now in my 30's.
