Comet Ikeya–Seki, formally designated C/1965 S1, 1965 VIII, and 1965f, was a long-period comet discovered independently by Kaoru Ikeya and Tsutomu Seki. First observed as a faint telescopic object on September 18, 1965, the first calculations of its orbit suggested that on October 21, it would pass just 450,000 km above the Sun's surface, and would probably become extremely bright.
Comets can defy such predictions, but Ikeya–Seki performed as expected. As it approached perihelion observers reported that it was clearly visible in the daytime sky next to the Sun. In Japan, where it reached perihelion at local noon, it was seen shining at magnitude −10. It proved to be one of the brightest comets seen in the last thousand years, and is sometimes known as the Great Comet of 1965.
The comet was seen to break into three pieces just before its perihelion passage. The three pieces continued in almost identical orbits, and the comet re-appeared in the morning sky in late October, showing a very bright tail. By early 1966, it had faded from view as it receded into the outer Solar System.
Ikeya–Seki is a member of the Kreutz sungrazers, which are suggested to be fragments of a large comet which broke up in 1106.

At first meeting, the boats have traveled a combined distance equal to 1 length of the lake; at second meeting, 3 lengths. Elapsed time and distance for each is three times as as great. Then at second meeting M has traveled 500 times 3 = 1,500 yards. Since this is 300 yards longer than the length of the lake, the latter is 1,200 yards.
The ratio of M's speed to N's equals the ratio of the distances they travel before their first meeting:
(500)/(1.200 - 500) = (5/7)

You have 14 lit candles in your room when a strong breeze blows out 6 of them out. You grab 1 of them to light up 3 before the wax burns your fingers and you place the lit candle back. You leave to grab some matches but when you come back 4 more are blown out. How many candles do you have in the end?
Idk the book was running low on puzzles so I tried making one myself. Hope y'all find it fun :soviet-heart: and idk talk and have fun.
Comets.
I cannot get over the fact that a large portion, if not a majority, of people agree the literal fucking end of the world is coming, and we KNOW IT IS, and we have known for FIFTY YEARS. and yet, any time there is even a RHETORICAL ATTEMPT to address it, you get fucking hand wringing and denial of the cold hard truths that the entirety of science has agreed are established facts and have been so for DECADES. WE KNOW climate change is a huge issue, WE KNOW how to solve it, WE KNOW who did it, and the most you get from people is a "yep, that sucks, I'm gonna do basically nothing about it", or worse people who agree and say "this makes me feel sad, can we not mention it". I am sorry the self inflicted total fucking collapse of society is a bit of a bummer to you
Capital and the workers in the west have for long had a common (short-term) interest in developing climate change denialisms. Not just the hard "it doesn't exist" type, but one for every set of beliefs, from "the foreigners should be the one to address it", to "let's just plant a lot of trees".
This alliance of interests is changing, though, as increased extreme weather becomes an undeniable fact. I believe these denialisms will wane in the short term future, and will have to be replaced by new ideas. The real tragedy is if the left fails to seize the moment and promote its own ideas to replace them.
as always, material conditions be doing they thing. young people are far more class conscious and climate conscious than other generations have been in the recent past, I have optimism no matter how naive it may be
the silver lining to all of this is that, I used to think the green capitalists were going to recuperate the green movement and deradicalise it to sure up capitalism from this contradiction. I now know that will literally never happen, and even if they try to implement it will still have the same issues. there ain't no fucking treats if the world ends to keep the working class from realising what you did and how all of this needs to end
Or even worse a "Well we tried voting and nonviolent protests and that didn't work, what else can we do?"
The best we can hope for at this point is that human extinction will be avoided (far from certain if we continue on this path) and that centuries from now after learning its lesson humanity eventually builds an awesome anarchist society. They'll probably call our time period "The Age Of The Mistake" or something.
I think the deaths of millions is bad and we should try to stop it
I do too. I just don't see it happening.
I would rather die on my feet as a naive bloomer, than refusing to try as a depressed doomer
