IBM Personal Computer (model 5150, commonly known as the IBM PC)

On August 12, 1981, the Personal Computer, (model 5150, commonly known as the IBM PC) was released. This machine (and its descendants) started the PC revolution. It was a very small machine that could not only process information faster than those millions-of-dollars huge computers of the 1960s but also hook up to the home TV set, process text and store more words than a huge cookbook, all for a price tag of less than $1,600.

Unsurprisingly, it suddenly shook the personal computer market. The specifications of the IBM PC became one of the most popular computer design standards in the world. Even today, The majority of modern personal computers (PCs) are distant descendants of the IBM PC.

Space Shuttle Atlantis STS-43 launch, August 2, 1991

On August 9, 1991, two STS-43 astronauts aboard the Space Shuttle Atlantis, Shannon W. Lucid and James C. Adamson sent the first e-mail from space. The astronauts used an Apple Macintosh portable computer and AppleLink, a popular service for Mac and Apple IIGS users before the commercialization of the Internet, offered from 1986 to 1994.

The recipient of the first e-mail from space was addressed to fellow NASA astronaut Marsha S. Ivins at Johnson Space Center. The message text read:

“Hello Earth! Greetings from the STS-43 Crew. This is the first AppleLink from space. Having a GREAT time, wish you were here,…send cryo and RCS! Hasta la vista, baby,…we’ll be back!”

Prehistoric Animals Life on Earth

No Comments on Largest dinosaurs ever lived [2023 update]

Identifying the largest dinosaurs ever lived isn’t an easy task, because it’s very rare to unearth a complete fossil. Furthermore, only a tiny percentage of these amazing animals were ever fossilized, and most of these “lucky” bodies will remain buried underground forever. So, we may never know exactly what dinosaur was the biggest (or the tiniest) ever.

Despite this fact, size always has been one of the most interesting aspects of these prehistoric animals. There are extreme variations in their size, from the tiny hummingbirds, which can weigh as little as three grams, to the titanosaurs, which could weigh as much as 70 tonnes, or even more.

Here are the largest dinosaurs ever lived.
