Το κείμενο εξετάζει την υπαρξιακή κρίση που αντιμετωπίζει η σωματιδιακή φυσική, καθώς ο Μεγάλος Επιταχυντής Αδρονίων δεν έχει αποκαλύψει νέα φαινόμενα μετά την ανακάλυψη του μποζονίου Higgs. Οι ερευνητές διχάζονται ανάμεσα στην ελπίδα για τη δημιουργία νέων, ισχυρότερων επιταχυντών και στην αξιοποίηση της πληροφορικής για την ανάλυση δεδομένων. Ορισμένοι υποστηρίζουν ότι ο τομέας απλώς διέρχεται μια φάση μεγάλης δυσκολίας, ενώ άλλοι φοβούνται πως οι απαντήσεις ίσως βρίσκονται πέρα από τις πειραματικές μας δυνατότητες. .

- Making ice requires more than subzero temperatures. The unpredictable process takes microscopic scaffolding, random jiggling and often a little bit of bacteria.
The best known ice nucleator is a bacterium called Pseudomonas syringae, which has a protein that can force water to freeze at around minus 2 degrees Celsius. “It’s so good that all the artificial snowmaking, at least in Utah, and some [other] places in the U.S., uses this bacteria to make snow,” Meister said.

Στις 7 Ιουνίου 2024, τα Ηνωμένα Έθνη ανακήρυξαν το 2025 ως Διεθνές Έτος Κβαντικής Επιστήμης και Τεχνολογίας. Γιατί το 2025; Διότι του χρόνου συμπληρώνονται 100 χρόνια αφότου η κβαντική θεωρία έκανε τα πρώτα βήματά της. Το βίντεο του Ευγενιδείου Ιδρύματος εξηγεί την ακτινοβολία του Μέλανος σώματος με εξαιρετικό τρόπο.
Πώς οι φούρνοι οδήγησαν στη θεμελίωση της Κβαντικής Φυσικής: Το Μέλαν Σώμα κ η υπεριώδης καταστροφή Πώς ένα κοινό φαινόμενο όπως η εκπομπή φωτός από τη θερμή ύλη (εκπομπή Μέλανος Σώματος) οδήγησε στην κατάρρευση της Κλασσικής Φυσικής και στη γέννηση της Κβα...

(...perhaps the concept of time—arrow or no—is nothing but “scaffolding” for the human brain to grasp at as we try to “label all the events that take place in the world around us"...)
How Does Time Work in the Quantum Realm? This Story Will Make Your Brain Explode (In a Good Way) Scientists studying a centuries-old mystery of physics suggest two “arrows of time” control the evolution of quantum systems

"Some philosophers have drawn a distinction between the concept of "explanation" and "description". Science, they would claim, can describe elements of the natural world but not explain them. For many scientists, this is a distinction without a difference. The Nobel Prize-winning physicist Steven Weinberg, an eloquent advocate for science's place in the realm of ideas, takes this distinction at face value - in order to demonstrate that science does indeed explain something."
Can Science Explain Everything? Anything? - STEVEN WEINBERG Some philosophers have drawn a distinction between the concept of "explanation" and "description".

Einstein's big insight that explained Newton's law of gravity For centuries, Newton's inverse square law of gravity worked beautifully, but no one knew why. Here's how Einstein finally explained it.
