Hedy Lamarr died #OTD in 2000 at 85.

In the 1940s, in an attempt to help the war effort, she quietly invented what would become the precursor to many wireless technologies we use today including Bluetooth, GPS, cellphone networks & more: frequency hopping. #WomenInSTEM
A glamorous black-and-white studio portrait of Hedy Lamarr, the legendary Austrian-born Hollywood actress and co-inventor of the frequency-hopping patent US 2,292,387. She is posed reclining slightly in an elegant chair, gazing upwards with a poised, captivating expression—softly lit to accentuate her striking features, including large expressive eyes with dramatic makeup, perfectly arched eyebrows, full lips, and flawless skin. Her dark, voluminous wavy hair is styled in soft Hollywood waves framing her face. She wears a polka-dot blouse or dress with a sheer overlay, adorned with a multi-strand pearl choker necklace and pearl earrings, evoking classic 1940s Golden Age glamour and sophistication. Black-and-white technical drawing from U.S. Patent No. 2,292,387, titled "Secret Communication System," granted on August 11, 1942, to inventors Hedy Kiesler Markey (Hedy Lamarr) and George Antheil. This is Sheet 1 of the patent figures, showing a schematic diagram of the frequency-hopping invention (a precursor to modern spread-spectrum technology used in Wi-Fi, Bluetooth, and GPS). Key labeled components include: a variable frequency carrier oscillator (with piano-key-like switches 31a–31h connected to a notched paper roll mechanism for synchronization), two oscillators (100kc and 500kc), a modulator, an amplifier, an antenna (23), a ground connection, and a piano-roll reader (with reels 37–41 and motor drive). The diagram illustrates how synchronized frequency changes between transmitter and receiver enable secure, jam-resistant radio communication, such as for torpedo guidance during World War II. Handwritten-style annotations and figure labels (e.g., Fig. 1) are visible, with the patent header noting the filing date of June 10, 1941.

French mathematician & physicist Émilie du Châtelet was born #OTD in 1706. #WomenInSTEM

Her magnum opus, 𝘐𝘯𝘴𝘵𝘪𝘵𝘶𝘵𝘪𝘰𝘯𝘴 𝘥𝘦 𝘗𝘩𝘺𝘴𝘪𝘲𝘶𝘦 (𝘍𝘰𝘶𝘯𝘥𝘢𝘵𝘪𝘰𝘯𝘴 𝘰𝘧 𝘗𝘩𝘺𝘴𝘪𝘤𝘴, 1740) covered the principles of knowledge, the existence of God, hypotheses, space, time, matter, the forces of nature & more. #physics
18th-century oil portrait of French mathematician, physicist, and philosopher Émilie du Châtelet. She rests her chin thoughtfully on one hand while holding a golden compass over an open book. An armillary sphere sits behind her right shoulder. Dressed in a luxurious blue silk gown with lace sleeves and a large bow at the chest, her powdered hair is elegantly styled. Painted by Marianne Loir circa 1745–1749, the portrait captures the brilliance of the woman who translated and expanded Newton’s Principia Mathematica and became one of the Enlightenment’s leading scientific minds.

I’m deeply concerned that the Six Nations could be put behind a paywall. It’s a key part of our nation’s sporting calendar. The Liberal Democrats are calling for the tournament to remain on free-to-air television so access for all rugby fans continues.

Life tip: If you want a smarter kid, teach your child to read as early as possible and instill in them a love for books. Because as soon as they can read, they can teach themselves.

The main instrument is a still shawm, a musical instrument of which the only surviving example was found on the Mary Rose.
