Evidence for the decay B⁰→μ⁺μ⁻ ! The LHCb experiment sees the rarest B meson decay ever !
In the image below the big peak is Bₛ⁰→μ⁺μ⁻ . That was well known for 10 years. But to its left is the small contribution from the B⁰. One in 10 billion B⁰ proceed to two muons.

A United Kingdom outside of the European Union faces a future as a small irrelevant island dependent on others for its power, food and protection. Time to reverse the stupidity of Brexit, rejoin and take position at the heart of Europe.

Nog een keer Jimmy: als Putin zich morgen terugtrekt uit Ukraine is het vrede. Aansluitend kan dan diplomatiek MET Rusland worden gewerkt aan de einde van deze krankzinnige situatie in Europa. Dan kan er veel minder geld naar defensie.
Lees hier mijn ingezonden brief in de Volkskrant.
Het is veelzeggend dat een oproep voor vrede in 2026 door verschillende columnisten, opiniemakers en politici wordt gezien als een oorlogsverklaring. Maar nadenken, pleiten en werken aan vrede mag nooit een taboe zijn. En zelfs dat mag je van de gevestigde orde tegenwoordig niet zeggen.
Kom morgen naar het Nationaal Vredesprotest. 13.00u op de Dam in Amsterdam.

‘Werken moet lonen’ is een vertrouwde slogan van rechtse partijen; maar ze kiezen er steevast voor om de belasting op werk te verhogen!
In plaats daarvan wordt er wél geld vrijgemaakt voor lagere lasten op vermogen & winst.
Dat is oneerlijk van VVD, CDA & D66 en slecht voor gewone mensen!

Der finnische Reaktor #Olkiluoto3 – das pro Megawatt teuerste jemals in Europa errichtete Kraftwerk – hat nach seiner problematischen Bauphase etwas (für Atomkraftgegner sic!) Unerwartetes gezeigt:
Sobald ein Kernkraftwerk in Betrieb ist, läuft es mit einer Zuverlässigkeit und CO₂-Armut, die von keiner anderen Stromquelle erreicht werden; die finnischen Strompreise spiegeln diese Tatsache seit der Inbetriebnahme Monat für Monat wider.
Olkiluoto 3 ging im April 2023 ans Netz, nach einer Bauzeit von 18 Jahren und Kosten von rund 11 Milliarden in Betrieb.
Die Zahlen zu Verzögerung und Kostenüberschreitung sind hinlänglich dokumentiert. Weitaus weniger Beachtung findet jedoch das, was seither geschehen ist.
In den ersten zwölf Monaten des kommerziellen Betriebs erzeugte OL3 9,6 Terawattstunden Strom – das entsprach 98 % der theoretischen Höchstleistung. Ein Kapazitätsfaktor von nahezu 98 % ist nach jedem weltweiten Maßstab und für jede Technologie außergewöhnlich. Damit übertraf der Reaktor die Leistung der beiden bereits bestehenden finnischen Reaktoren, die ihrerseits regelmäßig jährliche Kapazitätsfaktoren von über 90 % erreichen. Im ersten Betriebsjahr lief der Reaktor 340 Tage lang durchgehend, ohne planmäßige oder ungeplante Abschaltung.
Die Auswirkungen auf den Strommarkt waren unmittelbar und erheblich. Die finnischen Großhandelsstrompreise lagen 2023 im Durchschnitt bei 57 Euro pro Megawattstunde – 40 % unter dem Niveau von 2022, das durch die europäische Gaskrise geprägt war. Die kontinuierliche, CO₂-freie Grundlast von 1.600 MW aus OL3 verdrängte rund 6 Millionen Tonnen CO₂, die andernfalls durch Kohle- und Gasimporte entstanden wären.
Der Bau von OL3 war ein warnendes Beispiel. Sein Betrieb ist eine ganz andere Geschichte.

When the USSR collapsed, all the countries that had been behind the 'iron curtain' - the Warsaw pact countries - became democratic and elected their leaders, replacing the leaders that the USSR had imposed on them since 1948
These newly elected governments, aware of how ruthless their USSR puppet governments had been, decided to join NATO, to defend themselves against the return of Russian domination
This spread of democracy panicked the Russians,
who feared that democracy might dismantle the
authoritarian tradition that has been in place there
since the Communists set out to impose Communism on the rest of the world
Or, later, in the case of Putin, his aim to create the USSR once again
For those still in denial that NATO expansion had anything to do with Russia’s invasion of Ukraine, have a look at declassified files showing Britain’s Ministry of Defence prepared for war with Russia after expanding Nato – 26 years before the invasion.

WHEN YOU REALIZE THE BABY BOOM WASN'T JUST SOLDIERS COMING HOME HORNY.
It was soldiers coming home to the GI Bill free college, 0% down home loans, low-interest business loans.
It was strong unions. Pensions. A house that cost 2 years of salary.
It was confidence that the future was actually going to be better than the present.
That's what produced a baby boom. Not romance. Security.
You want a higher birth rate now?
Give people a future where they know their kids will actually be okay.
That's the whole formula. It's not complicated. It's just expensive, and nobody in charge wants to pay for it twice.

To revolutionise physics we need experiments, not AI
Yes and no. For many Physics problems where the fundamentals are well established and they can be reduced to applied Math, the answer is yes. Many others - including almost all of the most fundamental problems - require an entirely different paradigm before they can become amenable to mathematical problem solving. This is one of the deepest insights from the history of Physics that we have almost completely forgotten over the past half a century +. At some point AI may be able to provide us with such a deep insight, but I have not seen even a glimmer of such capabilities from the current models.

A reminder that there’s absolutely nothing stopping NATO aircraft from shooting down Russian drones and missiles over Ukraine except for cowardice and complete lack of strategic understanding.
🇷🇴 A Spanish F-18 fighter jet pilot on a #NATO air policing mission shot down a drone illegally breaching Romanian national airspace, the fourth unmanned aircraft the country has shot down this year, Romania's defence ministry said on Sunday.
