The Department of Energy’s liftoff report on virtual power plants is a must read.
Tl;dr — they are tools that allow a central orchestrator to tap into distributed solar panels and batteries and coordinate their output onto the grid to balance the load for everyone.

I have a soft spot for seemingly needlessly complicated (at least initially) mechanical designs that on further examination reveal an human’s desire to simplify its architecture to its essence
Something that lies in my head rent free:
No one says this part out loud - as part of the JST (Joint Strike Fighter - the program that led to the F-35) The Lockheed Martin X-35 was chosen over Boeing X-32 simply because the X-35 looked like a plane, not a cow

My parents visited this week, and my dad (aka Opa) studied aeronautical engineering. I think it shows in the paper airplane he made for the kids.
Meet Automabot, a really cool mixture of magic, IoT and programming.
It's maker Mario the Magician, performed several shows with it and it's a very crafted maker and magician.

Florida might make headlines for wild news, but it’s a goldmine for engineers! The state has extensive and detailed Digital Elevation Models (DEMs)—perfect for stormwater modeling and more. If you want to know how I use it, comment and I'll elaborate! ⌐◨-◨

NOAA dropped this banger of a dataset and I couldn't be more excited. 1-m resolution with the largest coverage we've seen in the states so far. For me this means increased accuracy in developing storm water models for large areas by directly quantifying impervious instead of using outdated generalizations!
I saw a tv report about a local start-up (here in Stuttgart) that has developed a microcontroller that, as far as I understand, works optically (photonic computing).
According to the company, it is supposed to be much more energy-efficient than conventional microcontrollers.
They‘ve already built a pilot production line.

Australian scientists have developed an advanced model of an artificial heart made from titanium. Thanks to the use of titanium, this artificial heart possesses special characteristics such as lightweight, high durability, and biocompatibility, meaning the human body accepts it well without adverse reactions.This artificial heart is designed for patients suffering from severe heart failure and can serve as either a temporary or even permanent replacement for the natural heart. Its design allows it to circulate blood without the need for a heartbeat and utilizes magnetic or mechanical pumps.Some key features of this titanium model:
Lightweight
High durability and resistance to corrosion
Reduced risk of blood clot formation
High biocompatibility and lower risk of rejection
This project in Australia was carried out through the collaboration of doctors, biomedical engineers, and material scientists, and is considered a significant advancement in the field of tissue engineering and medical implants.

3D Printing is an emerging technology that enables the production of physical objects from digital models. Unlike traditional manufacturing methods, which rely on cutting or molding, this technology uses a layer-by-layer construction process to create objects.
This technology is utilized in various industries:
✔ Healthcare & Medicine: Production of customized prosthetics, artificial bones, bio-organs, and even printed medications.
✔ Aerospace & Automotive: Manufacturing lightweight and durable parts to reduce costs and improve efficiency.
✔ Construction: Printing small houses and building components at high speed.
✔ Electronics Industry: Designing and producing printed circuit boards (PCBs) and complex electronic components.
✔ Fashion & Design: Creating custom clothing, footwear, and jewelry.

Polymers are large molecules composed of repeating structural units known as monomers. These macromolecules are widely used in various industries due to their lightweight, durability, and versatility. Polymers can be classified into natural polymers (such as cellulose, rubber, and proteins) and synthetic polymers (such as plastics, nylon, and polyethylene).
Types of Polymers
1. Thermoplastics – Can be melted and reshaped multiple times (e.g., PVC, polyethylene).
2. Thermosetting Polymers – Harden permanently after being molded (e.g., epoxy, Bakelite).
3. Elastomers – Have rubber-like properties and high elasticity (e.g., silicone, rubber).
4. Biodegradable Polymers – Environment-friendly alternatives that degrade naturally (e.g., polylactic acid).
Medical: Biodegradable sutures, drug delivery systems
Automotive: Lightweight components, tires
Electronics: Insulating materials, flexible circuits
Packaging: Plastic bags, food containers

Increasing scale changes everything about the system. Design that targets two scales breaks both ways
If you do so, you will never reach that point because the time it takes to build something grounded on theoretical constraints will make your work irrelevant

what happens when we stay high level?
I'm reminded of Moore's law as well (when I think about scaling inference time compute) I think in the 2000s? 10s? there was a shift from scaling the CPU / power efficiency i.e. Dennard scaling (because we started hitting the physical limits like 3~4 Ghz - and started moving to multi-core scaling, SIMD (single instruction, multiple data). Also just better branch prediciton, out of order execution
I think what's also interesting was this was also around the time that NVIDIA started to pick up CUDA in 07, GPGPUs, Google started building TPUs, specialized hardware for doing massively parallel tasks, which eventually found a gigantic home in AI

images-as-coordinated-truths mostly work where "form determines function" ... where the requirements of camera calibration are loose
for truths of something formless like gas composition, we'd want verifiably-calibrated labs that does things like chromatography ... such that "scale determines function"
verifiable labs-on-chips?

And "truth" in this case, I imagine a sort of "Popperian Truth" -- where 'truths' can only be tested and potentially falsified. Truth, in this sense, is provisional and contingent on surviving attempts at falsification.
And as I think of a verified truth layer, as an for an objective adjudicator to exist. Provide a shared reality layer where individual claims can be verified or falsified -- meaning you don't proclaim that there is an ultimate arbiter of abstract "Truth" with a capital T. Rather, it’s like a ref that referees sports, or something or rather

Those pincers are way too small, but this is a brilliant idea.

There’s a podcast about materials science called “Materialism” and the episodes usually have a lot of interesting tidbits. They sometimes use technical terms without explaining them, so some prior exposure to MS (e.g. through engineering) helps but I think most of the content is very approachable and interesting nonetheless.
Here are two episodes I liked:
- Stories from a materials salesman: https://open.spotify.com/episode/3aKOMMdAHAlSNiigOvSlws?si=ATMjytJHQg2YILHvuEA0Dg
- You don’t know anything about steel: https://open.spotify.com/episode/2myA5oLPbB5pdGaEHP20zr?si=12w2Bey1RKOzBu4s684B1w&t=997
