HUMAN MIGRATION AND CLIMATE CHANGE 10am Wed 27 Aug

🗓️ Start: Wed 27 Aug 2025 10:00 am
⏳ End: Wed 27 Aug 2025 11:30 am

Over the past million years human migration has been largely driven by climate change. Since the industrial revolution green house has emissions have resulted in human generated climate change. Average global temperature have risen to 1.4C above pre-industrial levels, with a projected rise of 2.5-2.9C by 2100. This will generate an estimated >1 billion climate migrants (external & internal) mainly from poorer equatorial countries. A managed population retreat to cooler northern countries is needed to minimise conflict.

Wonders of Evolution

🗓️ Start: Wed 10 Sep 2025 10:30 am
⏳ End: Wed 10 Sep 2025 12:00 pm

When, exactly 200 years ago in 1825, the young Charles Darwin arrived in Edinburgh to train to be a doctor, little could he have imagined that, just six years later, he’d be setting out on the epic voyage that would not only make him famous, but also change our understanding of the natural world forever. In this illustrated talk, Barry Zussman (Torridge u3a) will begin with an overview of how Darwin arrived at the theory of evolution by natural selection, followed by some fascinating examples of evolution in action, and in particular, the ingenious ways that certain insects have evolved to outwit their enemies, and some amazing plants that have evolved to outwit them.

Today, at 2pm BST, I'll be presenting "Exploring Alternatives to Mainstream Social Media" to u3a online learning events. Will include a brief history of social media platforms, some issues with the big ones and a look at the fediverse.

Will include a proposal that we create our own server https://u3a.social

I'll also mention instant messaging and search engines.

New findings near Black Hole Event Horizons

🗓️ Start: Mon 29 Sep 2025 5:00 pm
⏳ End: Mon 29 Sep 2025 6:30 pm

Speaker: Dr. Dan Wilkins
Kavli Institute, Stanford University

Recent breakthroughs near black hole event horizons are offering exciting new views into some of the universe’s most mysterious regions. Using powerful X-ray telescopes, scientists have observed light bending around black holes, just as Einstein predicted over a century ago.

They’ve also detected faint echoes of X-rays bouncing off material hidden behind black holes, something never seen before. These findings help researchers understand how matter behaves in extreme gravity, how black holes consume surrounding material, and how energetic jets are launched.

It’s a major step toward mapping the chaotic environments near black holes and unlocking secrets about space, time, and gravity itself.
