Former NASA engineer. Current CNselr 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.

    My first time to encounter this logic problem solving test was when i was a trainee on a bpo company. We were given pieces of paper, tape, and an egg... i dominate my team and lead the strategy. I asked my team to make balls for each paper and surround it to the egg secure each layer with tape generously. And we won!!!!

    I haven't ate plants in two weeks. All my energy is from meat since I'm on a carnivore diet... plants don't want to die so they do cause inflammation in some people, especially in Jordan Peterson and his daughter who probably would've died eating plants, just go look up her story, she only eats meat

    What an awkward video, clearly it tastes different to a real burgers, bills reaction is the most obvious to this. The trick is the burger sauce and garnish to hide the taste. He never even eats the burger patty he cooked at the start of the video.

    Except plants pollute too so you're hardly saving squat. Rice produce methane... etc. Big industry, including the one that Bill Gates runs, also pollutes a ton. Cars pollute a ton. But sure, the enemy is burgers. *eyeroll*

    Isn’t it amazing how kids say “your cheating” but I agree with Mark, it’s actually using it as an advantage. You could make the same argument that it’s cheating when the owner can select the next payout, for example every 30 games. Or like the other machines collect $xxx-$xxxx amount of money before paying out any Jack-pot.. so who is really cheating? Or getting cheated? Imagine Vegas !!!

    What have you done mark

  73. Michael Wise

    Why not incorporate single seed sets (including nutrition, deterrent, protection etc) in single dart-type canisters? That way, one drone could carry more seeds and plant more efficiently by simply dropping each dart. Final velocity and planting depth are variables that could be dealt with situationally, based on requirements.

  91. Garraway Prox

    For me it's like this - I enjoy the taste. I'm not a politically stuck dude who eats meat because "It's my god damn right!". I enjoy it, but I could swap to an alternative right of the bat. If you can make it taste as meat, be healthier and even cheaper then I'm going to cut meat of my life tomorrow. I couldn't care less.
