Don_DickleWhat are historically medicines found an opposite use for? Like Viagra being a heart pill but now a boner pill. Or Ozempic being a diabetic drug but now pretty much used for weight loss?
When was the % of CO2 in Earth's atmosphere at its lowest?
After watching the latest Veritasium video: why is the spin of a proton/electron decided at measurement, why not at creation?
After watching the latest Veritasium video: why is the spin of a proton/electron decided at measurement, why not at creation? - sh.itjust.works
I am not a boy because my parents observed my penis at the 12 week echo. I am a boy because the sperm cell that made me, carried the right chromosome. It was decided at fertilization. Even if my parents never observed me, I would still be a boy. The experiment described in the Veritasium video splits a particle in an electron and a proton. They must have opposite spin and that is measured at the time of observation. Than there’s a whole discussion about faster than light communication, but if the spin is given at the moment of creation, both will have the opposite spin from the start. It can still be random and measurements will still have a 25% failure rate. What am I missing? Can the spin change between creation and measurement? What happens if a particle doesn’t get observed, does it not have spin?
Yeast salt reaction
Yeast salt reaction - Lemmy.World
I make 9kg of bread every weekend (reasons). so when I wake up I start blooming the yeast: 3268gr of water, 109g of sugar, and about 20gr of yeast. I had to leave for something so I came back two hours later, it smelled amazing, next step is to mix in the salt (218gr) and flour (5440gr) , I usually put the flour first then salt. but this time I put the salt first. What happened? it fizzled like a soda, like mixing baking soda and vinegar, so many bubbles appeared immediately. I noticed because of the sound it made (was looking at the scale numbers). Obviously it cannot be a chemical reaction because salt does not really react with anything there, at most it kills some yeast cells before mixing because some parts would have high salt content. there has to be some cool biology involved. And I refuse to ask any AI for that
What's the best lecture you've wanted in 2025?
Florian HaasWhen it comes to cooking, my spouse is a bit of a germophobe and tends to prefer a plastic cutting board that can be cleaned in the dishwasher. I am more of a microplasticphobe and thus prefer wooden cutting boards that I clean with hot water, soap, and a brush.
Whose phobia is more in line with the current state of science?
Edit: Thanks everyone, I got plenty of helpful replies! See thread below for a very insightful link.
Timing dark energy
Why do December 11th and December 25th always end up on the same day of the week?
Do any computer monitor "dynamic range compressors" exist for moderating intensity and whiteness/blueness of light?
Do any computer monitor "dynamic range compressors" exist for moderating intensity and whiteness/blueness of light? - Sopuli
In music there is the very well established practice of placing compressors on audio signals that have too much jarring dynamics from quiet to loud and tend to hurt our ears and not feel aesthetically pleasant. However in the realm of human sight while there is flux and other screen blue light eliminators/eye comfort filters and a decent amount of dark mode support for a lot of software and webpages/browsers… it seems strange to me that I have never found a eye comfort plugin for a computer or phone that attempts to massage abrupt extremes as well as abrupt discontinuous changes in a wholistic measure of a display’s light intensity output. What I am describing would look like is when you opened a new tab from a relatively grey/dark mode dominated display picture in your web browser and the webpage that loaded was all white that instead of being a massive abrupt blast of white to your eyes the “light intensity compressor” would limit how fast the overall brightness of the picture could change and slow the speed down to a pleasant gradual change that ended up presenting the actual very bright display image only after working your eyes up to it. Note I am not asking for “apply dark mode” everywhere tools I am asking if any tools exist that can sit at the end of the image display pipeline and moderate dynamics so that sudden brightness changes were simply not displayed. I realize this isn’t really a directly a science question but since it involves somewhat complicated signal analysis and manipulation concepts I figured science was a better place for it. If none of these tools exist is there a hard reason they couldn’t?
