A Solid 20 Minutes of Useless Science Facts (ft. Hank Green & More!)

A solid 20 MINUTES of Useless Science Facts! After I went through this pain for 15 minutes, obviously it had to return - but which fact is the most useless?

Mate you don’t take the easy option of just stitching it together, you really make it much more engaging…and much more work for yourself! Great stuff!

[DrAndrewSteele]

This video is a complete waste of 20 minutes 41 seconds. I loved it! Thanks for having me!

[GabrielDemetriusSilva]

As a Engineer at the aeronautical industry I can say to you that there are REALLY strict rules on what is considered to be "the loads expected" on a airplane. Yes, the factor of safety can be considered "small", but the "expected loads" is actually higher than any regular operational load. The level of safety of a airplane is State of The Art in the engineering world. :) Fly safe, fly relaxed.

[omershalita]

Tommy: hey guys, please make sure that your videos are no longer than half a minute long
Wren: *stares intensely*

[kindlin]

2:14 As a structural engineer, I loved this entire segment. And I had heard of the the super low factor of safety of aircraft, but I believe it's more like 1.5. While in spaceflight, it routine gets down to below 1.25, or even 1.1 or lower, depending on how much that extra design capacity affects the weight and how variable the loads are.

Modern structural design mostly uses LRFD design, verse the ASD (Allowable Stress Design) being discussed with all of these factors of safety. FoS are easy to understand and implement (FS=5, *BAM, * you're much safer), but miss a lot of nuance is the statistical nature of the _maximum anticipated load_ that you expect your system to have to support/resist.

In Load and Resistance Factor Design (LRFD), you apply a factor to various applied loads, like wind, earthquake, self weight, snow and live loads, based on how likely they are to occur simultaneously (1.2D+1.0E+0.2S), and you also apply a different factor to the capacity side of things, based on how variable the type of fabrication is for that type of member (rolled steel = 0.9, welded connections = 0.75, brittle concrete = 0.65). Taken together, the Load Factors and the Resistance Factors are intended to provided a 1:10, 000 chance of failure of any given member experiencing its maximum design load.

Wren misunderstood the point a bit, so interesting :D

But also, his safety factor is based on the carrying capacity of the aircraft, which isn't the only safety factor to consider. For example, four-engined planes can still fly with just one engine running.

Did you just get EVERY sci Youtuber?
With that lineup you could start a Edutainment YT Rewind

[TristanSharman]

Fantastically useless video, it was an honour to be a part of it!

The only time I'm ever gonna see a guitar mistaken for a bass! LOVE IT!!!

[peppersalt]

14:03 the female mayflies you are referring to do not die 5 minutes after being born, but 5 minutes after they molt from their juvenile form.

[brettbarager]

As a person who is a "Wealth of Useless Information, " I appreciate being able to add this to my wealth!

[szymonsowicki]

5:05 Maria Skłodowska-Curie was actually Polish, not French. The fact that she was married to Pierre Curie and that she had a French citizenship doesn't make her less Polish, as she was born and raised in Poland. Her last name Skłodowska should always be remebered as it was her real name and Curie was taken by her as a way to connect to the French science enviroment, besides of course being connected with her husband.

[dylanpritchard]

This could have been 5 hours long and I wouldn’t have realized! I was just entranced by never ending facts!

[nothingtoseemiano]

Its fun to see which ones youve already known simply by watching creators like these so much, and its fun to learn something new

[jamesupton]

Love the eyes and ears fact. Makes so much sense when you think about how often one darts their eyes to try to locate a sound.

[anon_imowy]

Marie Skłodowska-Curie wasn't French, she was Polish, that's why the element she discovred is called Polonium not Frenchium

[HaydenTheEeeeeeeeevilEukaryote]

You can actually still hum with your nose plugged, just only for a short time before needing to stop to let the used air flow back into your lungs so you can push it back into your mouth and sinuses again. And this does technically allow you to hum. Fascinating. 6:30

[spacemanspiff]

I live maybe 20 minutes from Pando, and she's one of the most gorgeous creatures, especially in Autumn!

[guenthersteiner]

The scientist who named that fungus after Spongebob is a legend

[EpicSpaceman]

Love this, thanks for putting in so much effort to make it so interesting and entertaining!
