  When Dan Gelbert takes the time to make a video, you stop what your doing and give it 100% of your attention

  Being completely honest here - this and another video from the same person are some of the most fascinating things I’ve seen in a really long time.  This is giving me my attention span back.

  2020 has been an absolute rollercoaster and seeing the man, the myth, the legend Dan Gelbart bless our YT feed has absolved me of most of my ill will towards this year

  I love this man. He has a rare ability to explain only the bits one needs to tell his story. I wish he lived next door. My dad was an engineer and any answer to a science question I asked him started with pulling out his ballpoint pen.
