Supernova Discovered in Nearby Spiral Galaxy M101 Image Credit & Copyright: Craig Stocks

Explanation: A nearby star has exploded and humanity’s telescopes are turning to monitor it. The supernova, dubbed SN 2023ixf, was discovered by Japanese astronomer Koichi Itagaki three days ago and subsequently located on automated images from the Zwicky Transient Facility two days earlier. SN 2023ixf occurred in the photogenic Pinwheel Galaxy M101, which, being only about 21 million light years away, makes it the closest supernova seen in the past five years, the second closest in the past 10 years, and the second supernova found in M101 in the past 15 years. Rapid follow up observations already indicate that SN 2023ixf is a Type II supernova, an explosion that occurs after a massive star runs out of nuclear fuel and collapses. The featured image shows home spiral galaxy two days ago with the supernova highlighted, while the roll-over image shows the same galaxy a month before. SN 2023ixf will likely brighten and remain visible to telescopes for months. Studying such a close and young Type II supernova may yield new clues about massive stars and how they explode.

"mathematics is as close as we can get to perfect rationality" said the mathematician, who regularly relies on at least three theorems they no longer know how to prove. "on a fundamental level our job is about truth", they said, making their tenth sign error of the day

if you own k distinct colors of sock, you can draw k+1 arbitrary socks from your sock drawer and, by the pigeonhole principle, be guaranteed at least one matching pair. this is the only known application of combinatorics to the real world

A metallic-looking rock that smashed through the roof of a residential home in New Jersey’s Hopewell Township earlier this week is indeed a meteorite — a rare one about 4.6 billion years old, scientists confirmed on Thursday (May 11).
“It was obvious right away from looking at it that it was a meteorite in a class called stony chondrite,” Nathan Magee, chair of the physics department at The College of New Jersey (TCNJ), whose office was contacted by the Hopewell Township police soon after the rock was found on Monday (May 8), told Space.com.
Chondrites are primitive rocks that make up 85% of meteorites found on Earth. Most chondrites found to date have been discovered in Antarctica; only rarely does one crash in populated areas.
The New Jersey rock, which is about 6 inches long by 4 inches wide (15 by 10 centimeters), is a notable exception. It slammed into the Hopewell Township house, dented the floorboard, punched two holes in the ceiling and was still warm when it was discovered by Suzy Kop in her father’s bedroom around noon on Monday.

Butterfly Fractal Sequence-62,” acrylic on Dura Lar, 25” x 40”, 2023, Reginald Brooks

Butterfly Fractal 1 (BF1): original, base fractal based on the Exponential Power of 2.

Butterfly Fractal 2 (BF2): original, base fractal based on the Exponential Power of 2, but with the Running Sums (R∑) emphasized.

Butterfly Fractal 3 (BF3): based on cubing the exponents.

Butterfly Fractal 4 (BF4): the 10 fundamental parameters of every Mersenne Prime Square (MPS) are revealed by SAME fractal-pattern of BF1, only using the x, y and z values of a given MPS.

My friend Kaleigh is trying to get back from Kalamazoo, Michigan, to Indianapolis, Indiana. Ze needs help with transportation and money, and possibly finding a stable place to live, or at least a place to stay. Ze has errands ze needs to run here in Indy. Ze is in the process of appealing zir current ban from all IU campuses, and has made significant progress towards that.

Kaleigh has faced significant abuse at the hands of homeless shelters and police.

I've made previous posts for zir, and for about a week it seemed like things were finally getting settled, but things are getting worse again. Lyft has been charging zir extra fees, and because of that ze's already halfway through the SSI check ze got this weekend.

CashApp: KaleighOGrady.

Kaleigh has found a place in Kalamazoo where the rent is only $150/month. I'll be doing my best to help zir run errands while ze's there, but some of the things ze needs to do need zir to be present here in Indy for an extended amount of time.

In particular, ze needs to do 24 hours of court-ordered community service before zir hearing on May 25th, and ze needs to pick up mail items (including legal documents and zir SNAP card) from the various places ze previously stayed. Ze's trying to find out if ze can do zir community service in Michigan instead of Indy, and we're both trying to see if I could pick up zir mail for zir, but even in the best-case scenario, ze still needs more help than I can provide alone.

We haven't heard back from the public defender yet as to whether ze can do zir community service hours in Michigan, so it's looking like ze'll need a motel stay in Indy. I can provide at most $500 for this ($600 if I start skipping meals/mooching off friends), which would be enough for maybe 8 nights at most if we book the stay soon.

I'll be picking up zir SNAP card tomorrow.

I wasn't able to pick up the SNAP card before Horizon House closed today, and it turns out the Wheeler Mission only holds mail for 24 hours before returning it to sender, so that's probably going to create problems down the line. At least I've picked up the prescriptions that were ready at the Damien Center.

Kaleigh needs zir scripts ASAP, and I'll need gas money to get them to zir. My CashApp and Venmo are both regicide1997 (same as my Tumblr url). I also have Tips enabled on my blog if you prefer that. DM for PayPal because deadname.

Please do not donate to me if you yourself are in need. I get paid monthly, $1,700 a month. Shit's just been a bit tight recently.

More than 40 leading scientists have resigned en masse from the editorial board of a top science journal in protest at what they describe as the “greed” of publishing giant Elsevier.
The entire academic board of the journal Neuroimage, including professors from Oxford University, King’s College London and Cardiff University resigned after Elsevier refused to reduce publication charges.
Academics around the world have applauded what many hope is the start of a rebellion against the huge profit margins in academic publishing, which outstrip those made by Apple, Google and Amazon.
Neuroimage, the leading publication globally for brain-imaging research, is one of many journals that are now “open access” rather than sitting behind a subscription paywall. But its charges to authors reflect its prestige, and academics now pay over £2,700 for a research paper to be published. The former editors say this is “unethical” and bears no relation to the costs involved.
Professor Chris Chambers, head of brain stimulation at Cardiff University and one of the resigning team, said: “Elsevier preys on the academic community, claiming huge profits while adding little value to science.”
He has urged fellow scientists to turn their backs on the Elsevier journal and submit papers to a nonprofit open-access journal which the team is setting up instead.
He told the Observer: “All Elsevier cares about is money and this will cost them a lot of money. They just got too greedy. The academic community can withdraw our consent to be exploited at any time. That time is now.”
Elsevier, a Dutch company that claims to publish 25% of the world’s scientific papers, reported a 10% increase in its revenue to £2.9bn last year. But it’s the profit margins, nearing 40%, according to its 2019 accounts, which anger academics most. The big scientific publishers keep costs low because academics write up their research – typically funded by charities and the public purse – for free. They “peer review” each other’s work to verify it is worth publishing for free, and academic editors collate it for free or for a small stipend. Academics are then often charged thousands of pounds to have their work published in open-access journals, or universities will pay very high subscription charges.

Funny, saw a python article about using lambda inside filters and it was like "cool trick you've probably never seen!" and I was like. theres a reason for that. 1) lambdas are looked down upon for testing and maintenance reasons, 2) theres also very few scenarios where filter(lambda, iterator) is somehow a better choice than list comprehensions with an "if" in them, especially if you wrap that filter in a list() immediately after. I guess it is a fun trick but it's not particularly good code in most scenarios

however. if you havent seen zip or enumerate you should learn to use those as much as possible because they are actually good

There was a group of angels at the bar tonight. Super intense vibe, but they kept to themselves and didn't disturb the other patrons, except for one point when they all suddenly burst into cheers and ordered a round for the bar. I asked what they were celebrating. They told me that for a split second all of the air molecules bounced petfectly into one corner of the room. It's like their version of the dvd screensaver.
