If you're programming a game where a boat moves through water, you might be tempted (as I would) to change the V-shape angle of the waves behind the boat based on how fast the boat was moving!
What if I told you that that V-shaped angle is always 19.47°, regardless of how fast the boat is travelling? 😱
This pattern even holds true for a duck traversing a pond. 🦆
The envelope of these waves stands at a fixed angle, and the wake has a characteristic feathered pattern.
Just got my COVID booster and everything hurts. But what hurts worse was the pharmacist telling me that she’s had to turn people away WHO WANTED THE SHOT because their insurance providers refuse to cover it (manufacturers are charging ~$120).
If your insurance provider won't cover your booster (or if you don't have insurance) the CDC's Bridge Access Program can help! It covers no-cost COVID-19 vaccines until December 31, 2024, more info here: https://www.cdc.gov/vaccines/programs/bridge/index.html
PLoS has a survey about code and software sharing. It’s quick and easy to tell them why you, don’t have or have not and support a journal that is considering implementing policies for it.

Some Thoughts on Debate On The Internet:
What Good Debate Looks Like:
Hello, I was reading your post, and have some different thoughts on the matter. Here are some legitimate sources that back up my ideas. Thanks for listening.
What Bad Debate Looks Like:
Jesus Christ, what a ridiculous idea! Here is a personal anecdote and a podcast I heard about why you're an idiot.
Remember:
Unless you have a doctorate in the subject you're talking about (and sometimes even if you do) the point of debate is to learn something new, and challenge your own thoughts on the matter.
If this is a very personal matter that you feel really emotional about, take a minute to think or calm down before you respond. Passion is great when used in a controlled manner, but can come off irrational if it isn't.
Yep, you have the right to free speech, but people also have to right to ignore you, especially if you are being rude or dismissive.
Anecdotes are not evidence! Your life experience is not everyone's. That doesn't mean people don't care, they may just not understand.
It's better to make allies than enemies. Most of the people I've met on Mastodon, other than a few exceptions, have been left leaning and want similar things. Before you go off on a small issues, try to establish what you have in common.
Make sure you actually understand what a person is saying before you get upset and block. I've read posts that have seemed sexist, racist, or homophobic, but it was out of context or I misread it, it's great to ask questions. Also, remember you may have information that this person doesn't have about why something is inappropriate. Give that information in a kind way, with sources.

Oh my goodness, it worked! That message was tooted from the Newton :D here’s how it looked in action. #RetroComputing #newton
Mathematician Bernhard Riemann was born #OTD in 1826.
He made deep contributions to complex analysis and number theory, but physicists remember him for his work on the foundations of geometry. These insights provide the mathematical framework for general relativity.

Journal sends a review back to me because when I did not run the code and replicate the results.
My response: "As an unpaid anonymous peer reviewer who handles probably 30 manuscripts a year, I am absolutely not in the position of running and evaluating code any more than I am in the position of running gels to evaluate lab results. If this is important to you, I suspect you can find a consultant who will do it at a reasonable rate."
Am I the asshole?

This is an absurd bait-and-switch, and will only cause pain for customers.
Here’s the video I did about Boss Lee in April. It was inevitable that she was going to die after refusing chemo as a “scam” but it’s still sad. I hope her fans now realize ozone treatment, herbs, and essential oils don’t work. http://youtu.be/3DUTipa4fms
climate, optimistic
I tend to think most “holidays” are weird old traditions that don’t make sense to keep around; vestigial relics of a dead era.
But today is September 16.
On this day in ‘87, politicians and rulers from 46 countries gathered in #Montreal to negotiate and sign a treaty called the Montreal Protocol. This agreement, if ratified, would establish an international ban on producing substances that damaged the #ozone layer.
It was ratified by 197 independent states – every UN member – ignoring the complaints of the #CFC industry.
CFCs were banned, and the ozone layer hole has been gradually healing every year. The Montreal Protocol has been called “perhaps the single most successful international agreement”.
For me, that’s worthy of celebration.
Happy #MontrealProtocol day.
Today was ... interesting. If you followed me for the past months over on the shitbird site, you might have seen a bunch of angry German words, lots of graphs, and the occassional news paper, radio, or TV snippet with yours truely. Let me explain.
In Austria, inflation is way above the EU average. There's no end in sight. This is especially true for basic needs like energy and food.
Our government stated in May that they'd build a food price database together with the big grocery chains. But..

Theoretical physicist by training (PhD in quantum open systems/quantum information), University lecturer for a bit, and currently paying the bills as an engineer working in optical communication (implementation) and quantum communication (concepts), though still pursuing a little science on the side. I'm interested in physics and math, of course, but I enjoy learning about really any area of science, philosophy, and many other academic areas as well. My biggest other interest is hiking and generally being out in nature.
