Hey Matt, whoever is editing your videos is not using the correct settings to export them for RU-vid. Take this video for example. Right click on the video and select “Stats for Nerds” where you will see that RU-vid measures the audio in this video as 7.9 dB too quiet. You want that number to be at or close to 0.0. Anything below -5 dB is very noticeable. If your editor Googles “how to make sure audio is loud enough for RU-vid”, they’ll see plenty of results to fix this problem.

@richdobbs6595 5 месяцев назад

This reminds me of when I implemented a SCRIMP mold filling simulation when I was working at Dow Chemical. I hadn't consciously thought about gravity effects on the mold filling, but I had included the terms in my equations. Low and behold, when I first ran the simulation with a complex geometry of the mold, it did indeed fill up the bottom and work its way to the top. I had expected that resistance of filling the media would completely dominate gravity effects, but in this case wasn't the case.

@adampope5107 5 месяцев назад

That's why it's so important to model things. What we model in our heads is filled with so much (necessary) generalization that it often doesn't fit reality outside human experience.

@MeltCat_Amy 5 месяцев назад

I wanted to clarify something. Around 7:00, Matt marks off the pore closure depth on the shallower snow section, and keeps it at the same level as the deep snow section. Up until this point, I had been understanding the pore closure depth as being measured from the uppermost snow surface, so I would have expected the dashed line to be at a lower level than on the deep snow section. Is the snow nearest the primary lower ice level just being generally assumed to have the same packed density everywhere, or is the snow regularly cycled (blown away, etc)?

@backwashjoe7864 5 месяцев назад

@@MichaelOnines more likely, Matt just gave it a go, trying to be helpful.

@johnclements6614 5 месяцев назад

In soils the density is effected by the depth and time at that depth. If there were large moving snow drifts and wind etc cut valleys I assume that the pore closure depth would vary due to the variation in loads.

Hi Matt. I have jst come from your show tonight at the Cockpit Theatre. Had such a good time - it was a great evening and very funny. Thank you for giving us all so much of your time! I had a random question which i didn’t want to ask in front of the audience lol. However when you were talking about the Archimedean solids and you spoke about the truncated icosahedron which is often used to make a football it made me think. I’ve always wondered when you kick a football of this shape from left to right it will then bend from right to left in the air. However if you do the same with a smooth surface ball like the plastic ones I mess around with with my daughter, the ball bends the other way from left to right? Is there an interesting physics/mathematical reason behind this? It must be the way the air flows over different solids. Something to do with the Magnus effect but why it is different for a smooth ball I am not sure?

Very interesting! Back in university, longer ago than I want to admit, I first got introduced to computers doing mathematical modeling. The models were much simpler, involving basic mechanics, and they matched reality… until they didn’t. Introducing a very small variation in the physical experiment would make the model and reality diverge, and over a fairly short time, completely out of sync. All this modelling is very interesting as an intellectual exercise. But after 35 years of writing software and modeling various systems, I can only give a word of caution: all models are wrong. Some are useful. Hope this one will be.

@ABaumstumpf 5 месяцев назад

What i find fascinating: So often you hear the claim that when the ice melts that would cause the ocean-levels to increase so much that coastal cities would be flooded. Roughly estimated we got ~30 million km³ of ice, and 360 million km² of ocean. Simple enough - that would be a bit under 100m of sea level under the (very false) assumption that all ice is fully on land and that the sea-area is constant. But water from melting ice is less dense than sea-water and the thermal expansion of the oceans also contribute a lot, leading to a sealevel increase of roughly ~60m. That would be a big impact.
