@trevorsumner @tameralamiri This might be too little, too late, but imaginary numbers are in the physical world inherently: they are the underpinnings of fundamental chemistry and physics. But I think you're looking for this where multiplying by your conjugate is squaring for reals https://t.co/3YFMUulu0e

@wyolum @andyweirauthor So i* is - i, so:
i(-i) + 1(1) = c^2
1+1=c^2
c=sqrt(2), which it should be

The 🌡️☄️ #ClimateAsteroid doesn't _have_ to hit us. This is what I'm working on to help us all avoid it. This is what my team is working on, what @heliogeninc is working on and we are so excited to share it with you today #ClimateAsteroidAvoidance #ClimateAsteroidAvoidance

[Permanent Eko @opsimaths]

Excited to read this! @mathematish clued me in to his ep of @myfavethm a while back.

[Permanent Eko @opsimaths]

Great blog post using narrative, analaytical expressions, numerical examples, and graphs to explore an idea and communicate its importance to a broad audience. My phenomenal community college math teacher and mentor, John Sawka, would approve!

[Permanent Eko @opsimaths]

Oh yes, and chemists, physicists, engineers, computational scientists and mathematicians are all encouraged to apply.

[Permanent Eko @opsimaths]

Check out my website https://t.co/uVnSfzpnHF for more about my research and my group, and contact me with questions!

[Permanent Eko @opsimaths]

All come with the opportunity for joint mentoring, professional development, and travel, as well as interaction with a wonderful set of collaborators at research unis, PUIs, HBCUs, and natl labs. Family friendly practices, close to Yosemite. I also throw a mean dinner party!

[Permanent Eko @opsimaths]

Come work with us at #ucmerced! This posting lists one of multiple #compchem/#chemphys #postdoc positions available in my group. Come be a part of a dynamic community focused on #theochem and real support for #margsci. Email for addl details, and please RT!

But also I have to tell @xkcd & @explainxkcd that #Ivanpah by @BrightSource doesn't have any salt tanks: maybe you're thinking of #CrescentDunes in #Tonopah by @SolarReserve

"The Hertzsprung-Russell diagram is located in its own lower right corner, unless you're viewing it on an unusually big screen." another great Brouwer #fixedpoint entry for @mathyawp @evelynjlamb & @niveknosdunk https://t.co/IDgZ5k9eO9

[Matt Enlow @CmonMattTHINK]

In the calm before the storm (math exams are tomorrow), I'm trying to figure out how to tell whether a given 1-dimensional cellular automaton can be turned into a (realizable) friendship bracelet pattern. #iteachmath #mathart #Mathematica

I just got my copy of "Power in Numbers: The Rebel Women of Mathematics" by @Dr_TalithiaW!! And it features my grad school colleague Trachette Jackson on the front cover! Buy your own copy at https://t.co/0Q5g8LpKZG

#humblebrag I got this right and it's making me _way_ happier than I could have imagined thx @MohamedOmarPhD for the lesson #LinearAlgebra #Psquared #NullSpace #NoSpoilers #CounterExample #FTW https://t.co/FvGIi8g11T

Also to everyone I met today on & off of Twitter | @NovellaYColeman | @madprofessah | @DrLove_94 | and many more: thank you, it's been a great two days! I'm excited to follow the panel & #gerrymandr #hackathon #expertwitness & #independentcommission tracks even if only from #here

[David A. Gross @mathematish]

Well, this is my #gerrymandr stop. Thank you to all the speakers today | @GarciaBedolla | Greg Herschlag | Kelsey Kauffman & @TarenSK | Tanya Cecena Pellegrini & Jonathan Stein | Ellen Veomett | Karin Mac Donald & Denise Hulett | and organizers Emille Lawrence and @PaulAZeitz
