Silicone in my food?

Dimethylpolysiloxane is an anti-foaming agent derived from silicone found in a variety of foods, including cooking oil, vinegar, chewing gum, and chocolate. While the risk of toxicity is considered low, it's not a chemical you'd ordinarily consider to be "food." thoughtco.com

 "PDMS is added to many cooking oils (as an anti-foaming agent) to prevent oil splatter during the cooking process. As a result of this, PDMS can be found in trace quantities in many fast food items such as McDonald's Chicken McNuggets" wiki
"oral exposure of dimethyl polysiloxane did not result in any systemic adverse effects in any species and dose tested and there is no concern with respect to genotoxicity" ref

Berating Eponymns


"There is also another unmeaning custom, which it is still more essential for us to get rid of. I mean that of naming subjects of Nature, after Persons, who have plumed themselves with those childish ideas of their being the first discoverers of such or such things." – Charles W. Peale, c. 1799; unpublished writings. https://matthewhalley.wordpress.com/2022/03/29/eponymous-bird-names-feed-ornithologists-vanity-without-enlightening-the-science/

 "Just like statues, buildings, and street or suburb names, we think a reckoning is due for scientific species names that honour people who held views or acted in ways that are deeply dishonourable, highly problematic or truly egregious by modern standards," Thiele wrote.

SLA vs FDM 3D printing

 SLA vs FDM for those who aren't familiar, "SLA better quality but messy, FDM stronger and larger prints,"
"FDM is rolls of solid plastic that get heated and melted then deposited on a bed; resin starts as liquid and gets cured using UV light. FDM with the commonly used PLA filament is relatively easy and safe to use. SLA produces much higher quality prints but needs chemicals for cleaning the prints then curing using another device and requires gloves to handle and recommended masks for the fumes."

Clever woodworking bench design


What an ingenious build. The casters only touch the floor when it's raised - the half-ton unit only requires a single external lever, and no locking casters. The flip-top is really sturdy. And both systems are simple and quick to use. 

What?¿! There was a real life Lord of the Flies saga.

Today I learned - there was a real-life "Lord of the Flies" scenario, four years after the book was published. How did I not know this? Why hasn't there been a movie based on a true story? Incredible - "boys had set up a small commune with food garden, hollowed-out tree trunks to store rainwater, a gymnasium with curious weights, a badminton court, chicken pens and a permanent fire, all from handiwork, an old knife blade and much determination." One boy broke his leg and they set the fracture and he healed. https://www.theguardian.com/books/2020/may/09/the-real-lord-of-the-flies-what-happened-when-six-boys-were-shipwrecked-for-15-months

User error acronyms

Inside-joke terms for "user error" - I particularly like 

PEBCAK (acronym for "problem exists between chair and keyboard") and, if you scroll down to the "other languages" section, 

USB problem (usuário super burro), translated as 'super dumb user' and 

'BIOS problem' (burro idiota operando o sistema) translated as 'dumb idiot operating the system'.

Energy vault -flawed design


Problems with the energy vault
1) high carbon emissions associated with producing the concrete blocks, 
2) vulnerability of the crane design to wind, 
3) the limited storage capacity, and 
4) the potential for block damage and erosion. 
A more efficient and environmentally friendly alternative: pumped storage hydroelectricity, which involves storing energy by pumping water uphill and releasing it through a turbine when needed.


Biggest excavation in the world


0:38 it will take us about 7 years to remove overburden before extracting ore when we expand the mine 1000 feet further. 

The ore has about 1:1000 parts copper by weight. 
1:48 we've produced 19 million tons of copper from 8 billion tons of ore
