Everyone has a different perspective about what it means for humanity to live harmoniously with all the other life we share the planet with. I think itâs fascinating how those ideas and endeavors trickle down through engineering into the real world.

I'm glad you didn't post this yesterday, no one would have believed that fish can climb ladders.
-
There's a fish doorbell in the Netherlands too! They have a webcam set up with a livestream so people can ring the doorbell when there's fish waiting to pass through the boat lock
-
"A big part of engineering, is fixing the problems we've created in the past" If only more engineers would see it this way
-
Hi Grady, can you create a series of engineering used in High rise plumbing. How the pipes don't burst when buildings flex. How the pressure is controlled for each floor etc.
-
1:50 "You've probably seen a fish ladder before." I appreciate the confidence you have in me but no I've never seen a fish ladder before.
-
Fish reach the processing plant, the way is guarded by Gary the gatekeeper who offers a choice: You can be processed into fillets and other fish based products, or go upstream to procreate and further your species. Which do you choose...the former, or the ladder?
-
I love your self-deprecating humor, from the "engineer who dressed himself" to the "nothing like a grown man playing with a fish in his garage" comments. Always fun and informative videos.
-
USA: We need a carefully tuned, complex piece of infrastructure so as to not interrupt fish migration. Germany: FISH DOORBELL
-
"Engineer dressed himself today" XD I once got a compliment for my dressing at a family party and i had to say "My girlfriend dressed me." Same energy
-
Cue âthe salmon disguised in a trench coat taking the stairsâ Far Side.
-
as a fish, i can confirm this
-
Study for my mid-term â Learn about fish ladders â
-
Can you do a short on how you make your display tanks. What materials you choose and why, challenges and mistakes that can be made and what you use to create the colour, glittery effect and maintenance. Your displays are always so good!
-
You and Smarter Every Day are two of my favourite youtubers. I feel like the two of you could do a subject and the two of you would make completely different and both completely fascinating videos.
-
me watching the demonic-looking lampreys sidle up the ladder "Are we 100% sure we want all types of fish to be able to travel upriver?"
-
I'm not saying my cat showed up just because you kept saying fish but I am saying I am starting to think my cat understands the word fish...
-
You have a really nice demeanor and you're easy to listen to. I know you've probably been told this before, but it really is true. I genuinely enjoy learning from your videos.
-
In my country, people say fish ladders are a scam, now I know that it's not that fish ladders don't work, it's that badly designed fish ladders don't work.
-
It's really impressive what lengths these engineers go to create efishient designs to solve sofishticated natural problems. I wasn't even aware of these efforts before watching your last two videos.
