Science

The Widowmaker

Tech & Engineering

The Baghdad Battery

In 1938, archaeologists near Baghdad uncovered a clay jar with a copper cylinder and iron rod sealed inside. When tested with grape juice or vinegar, replicas produced about one volt of electricity. Some believe this “Baghdad Battery” was used for electroplating jewellery, others think it had ritual or medical uses.

No records explain its true purpose, leaving open the possibility that people were experimenting with electricity more than 1,500 years before it was “discovered” in modern science.

Entertainment

I’ll Be There for You

When Friends debuted in 1994, its theme song “I’ll Be There for You” by The Rembrandts was just a 45-second clip. But viewers loved it so much that radio stations began looping the short version until the band recorded a full single. It rocketed to #1 on the Billboard Hot 100 in 1995, making it one of the most famous TV theme songs ever.
