@CodysLab @Naitso @FinitePhysicist KE = 0.5*m*v^2. What is velocity relative to here?

@Naitso @FinitePhysicist Stop as in loose all kinetic energy and be not moving through the space that it is in.

what's your favorite physics fact that seems fake but is actually real?

@FinitePhysicist Light has angular momentum…

@parkrunAU That’s great news, but quite strange as NSW are currently getting 5x less daily cases but still shut across the board?

📢 Victorian parkrun community, are you ready? We are excited to confirm that parkrun events in Victoria are permitted to reopen this weekend 🎉 #loveparkrun

@fermatslibrary Numbers under the square root: nice

A way to define the Golden Ratio is the value of x for which the 3 vertices are collinear. The equivalent for rectangular boxes is called the Plastic Number named by the dutch monk Dom Hans van der Laan.

@AlgebraFact Sum of triangular numbers equals the sum of cubes. Pretty cool

@3blue1brown MM/DD/YYYY 🤮

Happy e day!

To celebrate the incredible DOUBLE ASR for Xu, 2 GAN11M Pro will be free givenaway. Like & share this post, leave you comment to join this event. Congratulations! #GANCUBE #GANGURUS #RuihangXu #Sub6 #Sub10 #DoubleAsR #GAN11MPro #Giveaway #CubePlay2.0

Ruihang Xu DOUBLE AsR & DOUBLE Giveaway! In Beijing Spring 2021 competition today, Ruihang Xu achieved a DOUBLE AsR with 3x3 avg 5.96s and 3x3 One-handed 9.94s. Double NR in Feb. Double AsR in Apr. Does it mean that we can look forward to DOUBLE WR someday?

@MarcelPoots @tquocan23 @Fazrulz 3rd fastest in the world.

@tquocan23 @Fazrulz What is a WR3? Please forgive my ignorance 😁

Ruihang setting WR3! Suspect he'll lower this pretty soon though.

@ABCscience @misterwootube Possibilities are T -> flip -> H, H -> flip -> T, H -> flip -> H and H -> flip -> H (repeated twice as 2nd coin has two head faces). The given information reduces the set to H -> flip -> T, H -> flip -> H and H -> flip -> H. Of these, 2/3 result in a head after flipping.

It's time for a Friday brainteaser! 🤓

@FlammableMaths Why you got Yooler’s number, 3 and current all in the same expression?

Sad Euler reaccs only

@parkrunAU Obviously that shiny blue one!

Our milestones shirts come in five colours. Which one is your favourite? And why? We'd love to hear about any recent achievements 👇 #loveparkrun

@biancatoeps @diabalotia @fermatslibrary That’s awesome

@diabalotia @MagicBattery @fermatslibrary I got this in primary school, I love Montessori education. 😊 (source: casaschool.nl/2019/06/28/het…)

A visual proof of the square binomial: (a + b)² = a² + 2ab + b² 🤓

@diabalotia @fermatslibrary I love that. Thank you

@MagicBattery @fermatslibrary this made me want to look for it, but it seems to be a little bit harder to visualise in its entirety, you have to split it into components or make an exploded diagram

@MaitlandCouncil Walka water works path pls

@wcrpaul @arduino @albertonaranjo @TDataScience They’re the best

@arduino @albertonaranjo @TDataScience We love our HC-SR04's... 😍

Building a sonar array with HC-SR04 sensors, Arduino, and Python: bit.ly/3ax7x4X

@shamuspsmith @UON_research Wow. That’s a lot!
