How Kodak found out about the atom bomb

Back in the late 1940s, Kodak customers began to lodge complaints that the film they purchased was bad.

Why?

Because the radiosensitive film was coming out completely foggy.

Little did Kodak customers know at the time, but the foggy film was a direct result of fallout from the U.S. government's atomic bomb tests - the Trinity Test in particular - in New Mexico in 1945.

The Woolwich Foot Tunnel Anomaly

When the Woolwich foot tunnel closed for repairs in 2011, it should have been a routine job. The pathway had been providing pedestrians with a quick route beneath the Thames since 1912. A century on, a few minor improvements were necessary.

But Woolwich residents will recall that the refurb of this much loved and much used walkway did not go according to plan.  When it finally re-opened it was 8 months behind schedule, having been closed for more than a year and a half. What the average Woolwich dweller doesn’t know, however, are the unusual circumstances behind this delay.

Mention the 18 month time frame to someone who worked on the Woolwich Tunnel job and you may be met with a mysterious smile. A year and a half may have seemed a long time to those who relied on the tunnel for their daily commute. But for those who were down there beneath the river, that time-frame has a different meaning. When one contractor tells me he aged 3 years on the Woolwich job, it is not a metaphor. For, deep down beneath river and clay, hidden from those above ground, something was occurring. That something was a time anomaly.
