THREAD. Need some #physics ideas to go along with your holiday presents? I have you covered.

Here is my list of some cool physics experiments I have done with toys and stuff.
2/ How fast are #Nerf darts? Video analysis included.
wired.com/2011/06/how-fa…
3/ What about the speed of the #Nerf vortex disks? wired.com/2012/01/the-fl…
More #videoanalysis
4/ Actually, that previous post was the second #nerf vortex analysis. Here is part 1.
wired.com/2012/01/the-sp…
5/ #Physics #homework (not a post). Estimate the power needed to run with this drag chute.
6/ #Nerf related - the nerf darts are at least close to the speed of a blaster bolt from #StarWars wired.com/2012/05/star-w…
7/ How about modeling the motion of a falling slinky? You should try this, it's awesome.
wired.com/2011/09/modeli…
8/ Of course, you should watch the @veritasium video that goes with this. It's an internet classic.

9/ Here is a super old analysis of the spring constant of a slinky. There was a post with it, but it decayed. vimeo.com/8426977
10/ What is the price of one @LEGO_Group block? An analysis using linear regression. wired.com/2014/08/lego-c…
11/ Why are @LEGO_Group expensive? The answer is because they are very precise. wired.com/2013/01/why-ar…
12/ What is the density of a @LEGO_Group block? wired.com/2016/12/heres-…
13/ You can make forced perspective with @LEGO_Group - just like in #TheHobbit wired.com/2012/12/how-to…
14/ Here's how to make a super simple pull-back toy car.
15/ Pretty much any toy you have can be turned into a physics project. I'll just stop here.

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

THREAD. For many it is the near the start of the fall semester. Here I will share my teaching and learning posts. Some of these are for faculty and some are for students.
2/ I'll start with posts that just deal with students. My first recommendation - ditch that scientific calculator. It's overpriced and not nearly as good as python wired.com/story/ditch-th…
3/ Three things to learn for physics lab: unit conversion, graphing, and looking past the instructions wired.com/2017/01/wanna-…

THREAD. Here are some of my favorite #MacGyver hacks - most of them you can easily do yourself. These could also make great projects for kids.
2. For each hack, I will give two scores. Difficulty (D) from 0-10. A 0 difficulty means you already did it and a 10 means you will probably mess up a couple of times.

The other score: Equipment (E) from 0-10. 0 means no equipment 10 is specialized stuff.
3. Make a magnetic compass with a paper clip and a float. D = 2, E = 3.

#Thread of responses from women in aerodynamics to the question, 'what would you like to see in order for women's career progression in your field to be sustained and better supported?'

Responses incl. career flexibility, mentoring and more women in leadership roles #WomeninSTEM
1. "I think young female engineers need to see more female role models and mentors in my field. Having a visible example of someone that looks like you and is succeeding in their field is important. Having an opportunity to meet with a mentor like that can be very powerful."
2. "I would like to see that any career promotion is based on own merits and value added to the company or the society independently of the gender. I want that women are measured with the same rules as men and are given equal opportunities."

Here’s my 2018 testimony. Out of many, I’ll share this one.

#thread
In November 2017 I had an idea to produce a masterclass series that would be watched for free by all and paid for by brands that care about educating and enriching people’s lives. I didn’t know any brand that wanted to come on, I wasn’t even looking.
I just knew that if I concentrated on doing a world standard job, the work would speak for itself.

Listen, that was a bit Naive.

January 2018, I went on a limb and bought equipment for shoot: Cameras, lights, etc. I was ready but only two instructors had agreed to do it.

Oh boy I feel a #twitch mentality discussion coming on.
Somebody stop me before it becomes a #thread .
Seriously 'gaming' the system. 'grind' . 'harming numbers' im seeing a lot of these terms. And don't even get me started on the 'leave your link and ill check out' stuff.
TOO LATE! Alright, I was saving this for a series of videos, but whatever - feels good to vent. First off, I know - who am I?
This Non-partner idiot talking like he has a clue about anything.
Valid point. And to be honest one I don't have the answer to.
This is only what I FEEL - and what I
believe. And compared to the 80,0000 folks I see per day randomly spamming Bullshit in desperation for 'the grind'? hell - I'd say a belief carrys
at least some weight.

I SPEAK TO THOSE OF YOU WHO THINK YOUR VOTES DON'T OR WON'T COUNT - so you decide to vote for the popular candidates or stay away from voting.

Let's think about the ALTERNATIVE and some possibilities.

#Thread
If you have been voting for the popular candidates or stayed away from voting, I am sure by now you understand the results of both choices haven't met your expectation.
The popular candidates always think they will win irrespective of what they throw at the people. They have the money so they can spend their way through the system.
