Kommen wir zu etwas Erfreulicherem: Meinem heutigen #90sHit des Tages - Tom Petty and The Heartbreakers "Learning to fly". Singt ruhig mit! https://t.co/sZulmxasAG
Scientifically speaking, a butterfly is at least as mysterious as a superstring.
When something ceases to be mysterious it ceases to be of absorbing interest to scientists. Almost all things scientists think and dream about are mysterious.
-- Freeman Dyson
Erwin Schrödinger on consciousness ✍️
Although I think that life may be the result of an accident, I do not think that of consciousness. Consciousness cannot be accounted for in physical terms. For consciousness is absolutely fundamental. It cannot be accounted for in terms of anything else.
- as mentioned in The Observer (1931)
The Fibonacci sequence isn’t just a math trick—it’s everywhere in nature. From sunflower seeds to galaxies, the universe has a secret love affair with spirals.
Karl Weierstrass (31 Oct 1815 – 19 Feb 1897) constructed what a function looks like that’s continuous everywhere but has no derivative at any point:
f(x) = ∑_{n=0}^∞ aⁿ cos(bⁿ π x).
The magnified inset reveals its fractal self-similarity at every scale.
“A mathematician who is not also something of a poet will never be a complete mathematician.”
Today this function underpins fractal geometry and models irregular real-world phenomena; from coastlines and turbulent flows in physics to stock-price volatility in finance and rough signals in engineering.
Maxwell's equations, formulated by James Clerk Maxwell in the 1860s, are four fundamental equations that describe how electric and magnetic fields interact and propagate. They unify previous discoveries in electromagnetism, including Coulomb's law, Ørsted's discovery of the magnetic field around a current, Ampère's law, and Faraday's law of induction. Maxwell's introduction of the displacement current completed the theoretical framework, predicting that electromagnetic waves travel at the speed of light and thus revealing the electromagnetic nature of light itself. Oliver Heaviside later simplified Maxwell's original 20 equations into the four vector equations used today, which underpin modern technologies such as radio, television, and telecommunications.
During the Rosary for peace in the Vatican Gardens, Pope Leo XIV reminded everyone present and praying around the world that all people must do their part to achieve peace. It must start with “small but important things, abstaining from every form of verbal or physical violence in daily life and also on social media.”
Neues Besucherzentrum für das #GartenreichDessauWörlitz: MP @schulzeeuropa & StM #Robra beim Baustart zu Gast. Das "Gelbe Haus" in #Wörlitz soll denkmalgerecht saniert werden. "Mit dem neuen Besucherzentrum machen wir dieses @unesco_de-Welterbe noch besser erlebbar", so der MP.
Serenade der @bundeswehrInfo für MP a.D. @reinerhaseloff: ein Abend des Dankes für 15 Jahre Einsatz für #SachsenAnhalt. MP @schulzeeuropa betonte: "Du hast unser Land durch schwierige Zeiten geführt, Vertrauen geschaffen und vorangebracht. #Danke für deine Arbeit!" 📷Ron Hartmann
Ende einer Ära: Die Bundeswehr verabschiedet #SachsenAnhalt|s Ministerpräsidenten a. D. @reinerhaseloff mit einer Serenade. Gespielt wird einer der Lieblingssongs des 72-Jährigen: "So einfühlsam habe ich "Learning To Fly" noch nie gehört, sagt der Alt-MP danach zu den Soldaten.
