#CSPC2018@ChiefSciCan mentions #Budget2018 reinvestments of 2.8B$ to create more collaborative infrastructure in govt labs and beyond. This is a once in a lifetime opportunity to get things right and elevate Canada in science leadership 🙌
Proponents of #SpaceForce think big. They thing space is big. But for security, #space is notably small. I explain.
Earth's land surface is divided into national territories. They're big enough to hide & hoard stuff & they can be controlled & defended by local regimes. +
This applies to national airspace, too. It is actually becoming easier for nations to defend their airspace. As long as nations stay out of each others' airspace (without permission) there is no problem. But above 100 km or so this changes entirely. +
For security purposes, space means mostly orbital space. Low Earth orbit, up to about 2000 km, is militarily important because it's close to the surface. Weapons such as space-based missile defense interceptors or any surface-strike weapons would need to be parked in LEO. +
First, thank you Scott for sharing your story along with many personal insights from your time in space. It's great to learn more about the long path to become an astronaut and all the immense effort behind the human space program.
While reading Scotts book I got to understand the scale of the challenges coming with living and working in space better. It starts with having no gravity assisting you with daily life, keeping yourself healthy and alert for the hostile environment you are living in.
THREAD - How about a bunch of blog posts on #Space and #Astronomy? Yes, I have more than you can imagine - especially since these are really just #physics topics. Hold on - because this is going to be a bit large.
2/ Here is an answer to my fav astronomy question EVER - "What would the phases of the moon look like if the moon was a cube?" wired.com/2015/09/moon-c…
3/ The great thing about the cube moon question is that it really tests if students understand phases of the moon rather than just recalling factual stuff. Here is my python model of a cube and spherical moon
1-Çin ile ABD arasında yaşanan ekonomik hegemonya savaşı, 2018 yılının başlarından itibaren yeni ve daha etkili bir evreye girdi. 2000’lerden bu yana dünya hegemonyasında ekonomik üstünlüğü ele geçirmiş olan Çin, bu hegemonyasını pekiştirecek yeni adımlar attı.
2-Trump, Mart ayının ilk günlerinde, “çok aptalca olan ticaret anlaşmaları ve politikaları nedeniyle”, ABD’nin yıllık 800 milyar$ bütçe açığı verdiğini ve buna bir son vereceğini söyledi. Ardından, çelik ithalatına %25, alüminyum ithalatına ise %10 ek gümrük vergisi getirdi..

As part of the #BlackpoolPIER#space#science in schools project, @rwwalsh and I have been asking Y6 children what sort of people scientists are. Was surprised at how many children said #scientists were 'good', 'kind' and 'helpful'. Going to post a few examples below (thread)
