Multipolar Fantasy: Russia and China Won’t Save Us libya360.wordpress.com/2025/05…



This #neonwoman was on the wall of an old grocery store. When the store closed, the #neon light was salvaged and now she serves coffee in a downtown club. 😀

Hi fellow Artists!
I made a small project last week to design, and 3D print a palette to fit inside a business card holder. This kind of palette is perfect for short trips, journaling or to share watercolor paints with your friends. Enjoy! #Watercolor #MastoArt #3DPrinting

I have been thinking for a while about the issue of anonymity in Web3 (and, more in general, anonymous transactions). The growing realization of the damage caused by decentralized financial technologies is nagging my cypherpunk self, who has been at war for a lifetime against invasive tracking, manipulative marketing, and surveillance capitalism. I collected my thoughts here: gagliardoni.net/#20250427_priv…

Spoiler alert: I'm not endorsing backdoors, but I think some middleground solution must be found.

The image shows a screen displaying the "UK Audience Vote" results for a competition, likely a music contest. The list is ranked from 1 to 12, with Malta in first place, Israel in twelfth place, and the other countries in between. The countries listed are Malta, Greece, Latvia, Finland, Albania, Estonia, Sweden, Lithuania, Poland, and Israel. The background of the screen is dark, with the text and numbers in bright colors, making them stand out. On the right side of the image, there is a person wearing a black shirt with silver embellishments, holding their head with both hands, possibly in a moment of emotion or reaction to the results. The person is wearing a bracelet on their left wrist. The overall atmosphere suggests a significant moment in the event, possibly a reaction to the audience's voting results.

Determine Fundamental Constants with LEDs and a Multimeter


There are (probably) less than two dozen fundemental constants that define the physics of our universe. Determining the value of them might seem like the sort of thing for large, well funded University labs, but many can be determined to reasonable accuracy on the benchtop, as [Marb’s Lab] proves with this experiment to find the value of Planck’s Constant.

[Marv’s Lab] setup is on a nice PCB that uses a rotary switch to select between 5 LEDs of different wavelengths, with banana plugs for the multi-meter so he can perform a linear regression on the relation between energy and frequency to find the constant. He’s also thoughtfully put connectors in place for current measurement, so the volt-current relationship of the LEDs can be characterized in a second experiment. Overall, this is a piece of kit that would not be out of place in any high school or undergraduate physics lab.

To use this to determine Planck’s constant, you need to use Planck’s relation for the energy of a photon:

E = hf

Get some Energies (E), get some energies (f), and bam! You can generate a value for h, Planck’s constant. The energies? Well, that’s a very easy measurement, but it requires some understanding of how LEDs work. [Marb] is simply measuring the voltage needed to just barely light the LED of a given frequency. (For frequency, he’s relying on the LED datasheets.) That translates to the energy of the photon because it corresponds to the energy (in electron volts) required to jump electrons over the bandgap of the semiconductor in the LED– that’s how the light is generated. Those photons will have the energy of the gap, in theory.

In practice, the LEDs do not emit perfectly monochromatic light; there’s a normal distribution centered on the color they’re “supposed” to be, but it is fairly tight. That’s probably why is able to [Marv] get to within 5% of the canonical value, which is better than we’d expect.

This isn’t the first time we’ve determined plank’s constant; it’s quite possible to get to much higher accuracy. The last time we featured this particular technique, the error was 11%.

State-backed Huaneng Group has launched 100 autonomous electric mining trucks in Inner Mongolia, the largest single deployment of its kind.

Equipped with Huawei’s AI, 5G-A, and smart battery-swapping tech, the "Huaneng Ruichi" trucks boost transport efficiency by 20% and slash costs. Plans call for 300 trucks by 2026, highlighting China’s push to digitize heavy industry already cutting mining costs by 8%.

If you’ve been thinking about subscribing to my Substack, now’s a great time to jump in. It’s free (unless you want access to the archive), and I post at least twice a week—sometimes more. Short stories, essays, poetry, and whatever else I can’t help writing.

Something special lands Tuesday morning: a new science fiction piece in the classic tradition. Would love to have you there.

Handball results? 🤣 & another useful phrase I've learnt is 'elbows out' . Old English is 'spikey!'

The Orthodox Jewish religion must be illegal in order for other religions to be freely practiced, because the orthodox Jewish religion denies the freedom of other religions

Must read from our Palestine newsroom: Israel just launched its offensive to permanently ‘conquer’ Gaza as Trump’s Arab Gulf tour wraps up

Israel announced the initial phase of “Gideon’s chariots,” the expanded ground invasion to permanently “conquer” Gaza, amid reports that Trump reneged on his deal with Hamas to lift the blockade, and will reportedly expel 1 million Gazans to Libya.

Tomorrow, Romanians head to the polls to vote for their new president, between far right candidate George Simion and liberal technocrat, Nicușor Dan. We analyze how the results could have massive ripple effects on the entire European continent.

Well that's a relief. Bet there will be a huge investigation into this voting round this year. In a week when at least another 300 people in Gaza have been killed.

And can we agree that until Israel stops the war they are suspended from #Eurovision now...

Maybe not as many protests votes against them this year? They scored very high in the popular vote last year too eurovisionworld.com/eurovision…
