Birthday of the mobile phone, World Aquatic Animals Day. What else can be celebrated on April 3

Today, April 3, is the birthday of the mobile phone, UNN reports.

It was on April 3, 1973, that Motorola engineer Martin Cooper first dialed the number and called the company's office from the first Motorola DynaTAC 8000X mobile phone, which weighed as much as 2.5 kilograms.

However, it took ten years before this phone became available to ordinary consumers. The phone cost four thousand dollars. It took 10 hours to fully charge the phone, and it could only be used for 30 minutes.

Also on April 3, 1973, IBM showed the world the development of the bar code, which was jointly created by Norman Joseph Woodland and Bernard Silver.

A barcode is a graphical information that is applied to a necessary object to identify a product.

Initially, barcodes were used to mark railroad cars so that railroad companies could identify incoming trains and prevent collisions.

The first product to be scanned with a UPC barcode was a package of Wrigley's Juicy Fruit chewing gum at Marsh's store in Troy, Ohio, on June 26, 1974.

Today is the birthday of the coffee grinder. This indispensable device in the kitchens of millions of coffee lovers around the world was patented by James Carrington on April 3, 1829.

Before the invention of the manual grinder, coffee beans were ground in a mortar or with ceramic or steel millstones.

Since 2020, zookeepers all over the world have been joining in the activities on the occasion of World Aquatic Animals Day.

Aquatic animals include not only fish, octopuses, corals, whales, and dolphins, but also polar bears, turtles, penguins, amphibians, and seabirds.

According to scientists, almost 1,000 species of marine animals are affected by ocean pollution. Already today, there are more than 500 places on the planet recorded as dead zones where marine life cannot exist.

You can still join the World Party Day today. The event was inspired by the science fiction novel Flight by American writer Vanna Bonta, which was published in 1996. The events in the novel take place in reverse time and end on April 3, 2000, with a large-scale celebration for the sake of human unity.

So, it was on this day that they started celebrating World Party Day.

According to the church calendar, today is the Day of Remembrance of St. Nicholas the Confessor, who lived in Bithynia.

Mykyta was a monk, preacher, theologian, and had the gift of healing. He strongly opposed the iconoclasts. For this he was thrown into prison, severely tortured, but later released.

Christians also remember the holy martyr Theodosia, who also opposed the iconoclasts. The woman was brutally tortured for seven days, and on the eighth day she was beaten to death. Theodosia was buried in one of the monasteries of Constantinople.

Mykyta, Ivan, and Fedosia celebrate their name days on April 3.
