Which will jump higher?

Show thread

Is it better to jump with a long foot or short foot?

The cases below only differ by whether the in-lever or out-lever is bigger. Which will jump higher?

Ignore contraction dynamics & imagine the body is constrained to go straight up.

Answer and discuss below 👇

Thanks to all who made it to my talk at ! For those who couldn't, here's a prerecorded version youtu.be/BIwkG6a5WEo

Watch to find out when it's better for a foot to be a foot vs a leg... And how toes are a bit like wheels 🦎🛞

What does this device have to do with feet? To find out, come to my talk Fri at 9:30 in Tinto for the Open session: "Plantigrade feet avoid work through serial linkages"

You might even get a copy to take home (while supplies last)! 🦎👣

Hoping to connect over here with #evolution #biodiversity and #biomechanics folks! Will aim to post and support others. Here is a cool surgeonfish (Ctenochaetus) we dissected recently.

For the record, I acknowledge that the wrist contacts the ground, so the forelimbs are unambiguously plantigrade. To my eyes, though, the hindlimbs are digitigrade.

Also, not everyone agrees in the literature; some authors explicitly say mice are digitigrade - e.g.

Are and plantigrade or digitigrade?

I've seen a loooot of studies that code them as plantigrade (e.g.
doi.org/10.1073/pnas.181432911)

... but their ankle is well above the ground (e.g. video from doi.org/10.3389/fnins.2016.000)

What am I missing? 🐀

Can you see the bat sleeping in the snow?❄️
The Ussuri tube-nosed bat (𝘔𝘶𝘳𝘪𝘯𝘢 𝘶𝘴𝘴𝘶𝘳𝘪𝘦𝘯𝘴𝘪𝘴), found in Japan, Siberia, & Korea, is one of only two animals known to hibernate in snow- the other being polar bears.

Another #introduction post for all the new Twitter people (and just new people in general!). A little about me: I’m Sabrina - I’m a #writer (some #scicomm) and #author of #ScienceFiction (and #ClimateFiction and #dystopian) #books - my series Aestus was on the Amazon hard #scifi bestseller list recently. 😊 I also do #archery and #photography and enjoy #hiking - I would love to get into #astrophotography. I am learning #German and really enjoy good convos/coffee/tea. Sry for so many hashtags 😅

Just seen on Mastodon that the Sony/BMG royalty dispute means Rick Astley's "Never Gonna Give You up" is now blocked globally on YouTube. Playing just yields a "blocked in your region" message.

Absolute end of an internet era. 😔
