Former NASA engineer. Current JPreporterr and friend of science.
Answers to some common questions:
1) I studied Mechanical Engineering in School. I did my undergrad at BYU and Masters at USC.
2) I worked for NASA JPL for 9 years, 7 of which were working on the Curiosity Rover (I made a video about it you should def totes watch cause it's probably my favorite of all my videos). I founded a company called Digital Dudz on my nights and weekends while working at NASA (also made some videos about that) and sold it to the guys who make Morphsuits in the UK. As part of the sale I quit my job at NASA and worked for them coming up with all their new costume ideas for 2 years. Recently, I was presented with an opportunity to return to my Engineering roots to come do some ideation type of work for a tech company near San Francisco.
3) Link to free and therefore substandard build plans for my custom workbench can be found below.

    The problem with your experiment was that you put the cows blood with all the other tests thus possibly effecting the results. The control of the whole thing got screwed up. You should only do a control and one other thing at a time.

    It would help a lot if you give the whole nutritional profile instead of just protein and calorie, at the end of the day its all about a balanced diet for a healthy living and a vegan diet as far as I know is not considered to be a balanced diet and requires supplementation or costly alternatives like almond milk I guess. Would like more clarification on that.

    For the most part I believe plant-based meat is good but why do none of these channels look at the major economic impact this would have on the work-force. How are you going to discuss this topic but not mention how there are millions of individuals employed by the agricultural industry? Do they just all magically find a new job lol.

    Imagine thinking cow farts adding to climate change, he's getting his stuff from AOC who know nothing. Why don't we get butt plugs for cows to stop farting? Or just kill them off, nothing will work cause PETA is all about saving animals and they won't allow killing animals and butt plugs won't work. And plant-based products may seem healthy but adding soy just makes anything really unhealthy. It seems like you did a lot of research but not enough, it seems you are getting this info from the MSM. I love to workout and I did a lot of research just to know what kind of food I need to eat, there are some parts you left out just to make it seem good but nowadays people are too lazy just to do their own research.
