Publisher's summary
"Terra in vista - La scienza e la tecnologia spiegate a mio figlio" è un programma di Radio24 di divulgazione scientifica per ragazzi: condotto da Federico Taddia e dal filosofo della scienza Telmo Pievani .
Che cos'è il laser? A cosa serve? È pericoloso? Esiste davvero la spada di Guerre Stellari?
Ospite della puntata è il prof. Alberto Diaspro, Direttore Scientifico del Dipartimento di Nanofisica dell'IIT, Professore ordinario di Fisica Applicata dell'UNIGE, Presidente del Consiglio Scientifico Festival della Scienza.
Per capire meglio il funzionamento del laser ecco poi l'esperimento proposto da Agnese Sonato, caporedattrice della rivista scientifica per bambini PLaNCK.
Infine chiudiamo con una poesia dedicata al tema del programma, scritta e interpretata dalla poetessa per ragazzi Chiara Carminati.

Eight years ago I fell into a secret summer fling with my best friend’s little sister before our lives went in different directions. Now, I’m the grumpy to Juliet’s sunshine on a popular dating podcast we host, and when a wealthy fan gives us a charming coastal cottage as the biggest thank you ever, we head to the town where I grew up to give it a makeover. And find the house has only one bed. Located under a mirrored ceiling.

Story5 out of 5 stars 449
There is no bigger public health story now than the collapse in youth mental health. The numbers are terrifying and dominate our headlines. There has been much debate over how we got here, and what to do next, and bestselling author and social psychologist Jonathan Haidt is at the white-hot center of that discourse. Haidt has spent his career speaking wisdom and truth into the most difficult landscapes—communities polarized by politics and religion, campuses battling culture wars, and now the perfect storm contributing to a public health emergency for Gen Z.
