@mattlanza How many points of downforce from those horns? Do they flex like the front wing?

F1 should do a race in Houston, except it’s just surviving a trip around all of 610.

@CalumDouglas1 Very cool. I'm curious exactly how it as used. If you have the actual vertical profile of pressure and temperature, you can calculate the altitude as a function of pressure very closely without relying on the usual semi-empirical standard-atmosphere relationships.

A lot of you were very close, but not quite. Its a "Baro-Thermograph", and was made by the National Physical Laboratory for the Bristol altitude records in the 1930`s. To get really accurate altitude measurements you cant just use pressure at very high levels because you get near the Tropopause where the equations for altitude vs pressure change.

If anyone can guess what this specific box is and what it was used for I`ll fall off my chair. Hints: Date range 1937 ish, British Goes in an aeroplane Has a drum inside Measures things...

There are two ways to get a strategic plan. One is to use 28 months of meetings, working groups and several outside consultants. The other is to lock five people up at the university lake house for three days with just enough whiskey. Guess which one we used!

@MEOrive At a time when we keep being told that KU has too many buildings and that we need to downsize our footprint, the B-School asks us to hold their beer. 🤦‍♀️

@AkAstronomy @KUPhysicsAstro Sounds fun! We're in the same non-roach-free building for the foreseeable future, but maybe we can find something across campus.

@AkAstronomy I was dreading it because the trailers had this very dude-bro country-music vibe, but I've heard it's not all that obnoxious.

@AkAstronomy I’m embarrassed to say I haven’t seen it yet. It was on my to-do list for summer but was preempted by New Adventures in Respiratory Viruses. I hope to see Twisters soon, though.

@AndrewDessler Ohhhhh, I ask this question in thermo, with a Simpson's reference to Homer sitting in front of the open fridge.

Thermodynamics 101 failure. Why is this "spot cooler" not actually cooling the area? In fact, it's warming it.

@DrCats_Climate @ku_ams It wasn't too bad when it passed through Lawrence and barely woke me up. HRRR did a good job on the timing and placement.
