@techforeveryone.bsky.socialMarconi sent a radio signal across the Atlantic in 1901, when physics said the earth's curve made it impossible.
That completes Web & Wireless: 5 innovators, 4 bands, 20 free worksheets. Signal to protocol, in order.

@techforeveryone.bsky.socialMarian Croak holds 200+ patents, many on voice over IP — moving calls off telephone circuits and onto the internet.
Unpopular inside a phone company at the time. Every video call your students make is downstream of it.

@techforeveryone.bsky.socialHedy Lamarr — 1940s film star, and in 1942 co-patented frequency hopping to stop torpedo signals being jammed.
Spread-spectrum ideas from that family sit under Wi-Fi, Bluetooth and GPS today.
Free worksheets, all 4 bands.
@techforeveryone.bsky.socialStudents think the internet is a thing — cables, servers, a place. It's closer to an agreement about how to talk.
Vint Cerf co-designed TCP/IP: break it into packets, send by any route, reassemble at the end.
Free worksheets, all 4 bands.

@cs4hall.bsky.socialOur windowless CS lab often feels cold and sterile.
Thanks to DonorsChoose, today I put up our first wall of fairy lights and fake plants. 🌿✨
Making a computer lab warm and inviting helps every student feel like they belong here.
