U.S. stock ownership by U.S. households and nonprofits hits all-time record.

After 16 years and $1.83 trillion, I finally understand what #Bitcoin truly is.

It’s not digital #gold ,
not a payment system,
and not even just money.

Bitcoin is the first system in human history where trust comes from physics, not politics.

Here’s what that means 👇

Your bank account exists because the government allows it.
They can freeze it, print more money, or change the rules anytime.

Bitcoin exists because of energy and math.
Every block costs about $281,700 worth of electricity to create.
You cannot print energy, and you cannot change physics by voting.

To change even one day of Bitcoin's history, you’d need $40 million of electricity.
To change one day of banking history?
Just one phone call.

This is why Bitcoin keeps going.
Not because of price.
Not because people “believe.”
But because of math.

📌 Metcalfe’s Law predicts Bitcoin’s price with 90% accuracy over 15 years —
the same math used to explain how viruses spread or how earthquakes chain-react.

📌 Game theory explains why nobody has ever successfully attacked Bitcoin in 16 years —
the same logic that stops nuclear wars and keeps traffic working.

📌 Thermodynamics explains why attacking Bitcoin costs more than defending it —
the same physics that makes fake gold impossible.

Three scientific laws.
Sixteen years of real-world proof.
$1.83 trillion in value supporting it.

All other money in history asked:
“Do you trust us?”

Bitcoin asks:
“Can you do the math?”

For 5,000 years, money depended on trusting kings, priests, politicians, or central banks.

For 16 years, Bitcoin has depended only on verifying physics.

You don’t have to “believe” in Bitcoin.

People didn’t believe in the internet either.
In its 16th year (2005), many thought it was still a fad.
Yet today, you’re reading this because of the internet.

Any technology that removes the need for trust always wins.
Always.
Maybe not today.
Maybe not this year.
But eventually.
Because #physics is patient.
And physics never negotiates.

Sniegs, iespējams, nav tik inerts, kā šķiet. Jaunā pētījumā, kas publicēts žurnālā Nature Physics, atklāts, ka parastais sniegs var ģenerēt elektrību, kad tas tiek locīts, griezts vai stiepts - īpašība, ko sauc par fleksoelectricity.

Pētījumu, kuru vadīja komandas no Katalonijas Nanomateriālu un Nanotehnoloģiju institūta (ICN2) Spānijā, Sjaņas Džiaotongas universitātes Ķīnā un Stonī Brūkā universitātes ASV, atklāja, ka sniega elektriskā uzvedība mainās ar temperatūru, apstrīdējot ilgi turētās pieņēmumus par vienu no Zemes vispazīstamākajiem materiāliem.

Atšķirībā no piezoelektriskuma, kuram nepieciešama specifiska kristāla simetrija, fleksoelectricity var rasties jebkurā materiālā. Kontrolētos laboratorijas testos sniega plāksnes locīšana starp elektrodiem konsekventi radīja elektrisko potenciālu, atspoguļojot uzlādes, kas novērotas vētru mākoņu sniega sadursmēs, kas izraisa zibeni. Ļoti zemu temperatūru apstākļos pētnieki arī konstatēja ferroelectric slāni uz sniega virsmas, kas spēja mainīt polaritāti kā magnēts.

"Šis raksts maina to, kā mēs skatāmies uz sniegu: no pasīva materiāla uz aktīvu materiālu," sacīja galvenais autors Xin Wen no ICN2.

Atklājums novieto sniegu blakus attīstītām elektrokeramiskām materiāliem, kas tiek izmantoti sensoros un kondensatoros. Tas var arī palīdzēt izskaidrot dabiskos elektriskos fenomēnus pērkona negaisos un iedvesmot nākotnes tehnoloģijas, kas izmanto sniega pārsteidzošo elektro-mehānisko daudzpusību.
