See on you Mastodon @gregputzel@mstdn.science

@divbyzero I have an earlier "edition" where Euclid's proof has a mistake (it was assumed that p_1 * ... * p_n + 1 is itself prime). Glad to see they fixed it.

My friend got these pudding cups. (As in, “the proof is in the pudding.”)

If the plane is going in circles around you, then that ratio of speeds IS the angle (in radians).

A plane flies perpendicular to the line of sight. Its sound lags by some angle. The sine of that angle is the ratio of the plane's speed to that of sound. You're welcome.

Normalize using z scores.

If Wordle words were selected randomly and independently, you would expect at the very least one duplicate each year, usually at least 5 in fact. You're welcome.

Congress needs to pass universal background checks, ban assault weapons and high-capacity magazines, and confirm Steve Dettelbach as head of the ATF. It’s time to turn this pain into action.

Every American CEO, every corporate leader, every company based in Texas (@HP, @Oracle, @AmericanAir, @SouthwestAir, @WholeFoods, @Dell, @HEB) has a moral responsibility to publicly join the coalition demanding stronger gun laws. Today.

The idea that an 18-year-old can walk into a store and buy assault weapons is just wrong. What in God’s name do you need an assault weapon for except to kill someone?

It takes a monster to kill children. But to watch monsters kill children again and again and do nothing isn’t just insanity—it’s inhumanity.

R question. Let's say that df$A is "nested" in df$B if knowing the value of A tells you the value of B. What's the easiest way to summarize which pairs of a dataframe's columns are nested?

@lixinxunle @Bilum6 @_alexafluor @ycharzy Congratulations Xin! It was a privilege to participate in your project.

We'd like to express my gratitude to my incredible colleagues, Irina @Bilum6, Greg @gregputzel, Alexa @_Alexafluor, Yang @ycharzy, Meghan, etc. for providing so much technical support and helping to put the puzzle pieces of this project together.

It's wonderful to see our paper from the @Ilievlab out. Our paper was submitted just prior to the pandemic. After the Iliev lab was temporarily shut down due to Covid, it took us two years to revise this paper, and we are so glad it is finally available to the community.

@BioMickWatson Is there a preferred way of doing this?

Oh, and you should probably remove plasmids from your taxonomy database before doing read or contig classification....

Could two followers please copy and re-post this tweet? I'm trying to demonstrate that someone is always there, especially at this time of year. Call 800-273-8255 (National Suicide Prevention Helpline US). Just two. Any two. Copy, not retweet. Let’s all look out for each other.

@lixinxunle We ended up reading the book about a pig named Olivia. It was fine.

@gregputzel Which book did he finally choose ? Lol 😂

Dear @POTUS (& @PressSec) An ambitious, but simple plan to convert holidays into an time to REDUCE #COVID19 1) Give every American 4 #RapidTests 2) Ask every American to test on Dec 25, 28, 31, Jan 3 3) Simultaneous mass severing of transmission chains can collapse outbreaks

@David_Erroll Ok but can we name it after someone else please?

A convenient unit for describing fluxes in the H20 cycle of our planet is 10^12 cubic meters/year. Which is a thousand cubic km per year. Have a nice day.

In a @LtlFreeLibrary I found "Another Planet" by @tracey_thorn, from which I learned that "The Ballad of Lucy Jordan" (as heard in the movie Thema & Louise) was written by Shel Silverstein. It would be hard to diagram how interconnected things are. youtu.be/S7GoTAmvxw0
