[Harris Lab @FluidDanamics]

New #harrislab open-source hardware released!

Introducing FIEVel: A Fast InExpensive Velocimeter based on an optical mouse sensor.

The device can nonintrusively measure pointwise x-y velocities at rates up to 6.4 kHz, all for around $100.

#DailyMechanician Shelby Hutchens explores fracture in soft solids & physico-chemo-mechanics of solid-fluid composites, often with elegant experiments. A '16 paper studied mechanisms leading to pressure drop in cavitation rheology, as well as means to quantify fracture toughness.

Dear friends who write NSF GRFP rec letters, this year rec letters are due BEFORE the applications, so about 10 days earlier than normal on Oct. 11. Please don't let NSF's deadline change on rec letters screw over the applicants in your lives.

@AlexanderRKlotz Well read the whole thing, but these are a very "formula" type of letter in my experience.

❗️Friends, this is important. I ask for shares and spreading information, especially by my followers from Canada. This can set a precedent.

The Russians at War film by Russian director Anastasia Trofimova will be shown in Canada at the Toronto International Film Festival.

The movie romanticizes Russian soldiers, the aggressors who commit acts of violence in Ukraine every single day.

Showing this movie sends a false and morally wrong message that it is the Russian soldiers who should be pitied.

Russians soldiers go to war mostly voluntarily. To them, it is a chance to earn money. Ukrainians go to war because we have no choice, because we are fighting for our very existence. To pretend that experiences of Russian soldiers are on the same scale with Ukrainian suffering is utter cynicism and distortion of reality. It disgustingly diverts attention from the victim to the feelings of an abuser.

If people want to know what Russian soldiers are really like, they can watch Intercepted by Oksana Karpovych or 20 Days in Mariupol by Mstyslav Chernov.

Narratives are important. Ukraine is fighting for her survival and independence. Russia is fighting for Putin's imperialist ambitions. This is the crucial difference.

Please share this post with whomever it might be useful or write your own, tagging @TIFF_NET. Thank you.
