🇳🇱🇬🇧 The "Royal Prince" and Other Vessels at the Four Days' Battle, June 1666, during the second Anglo-Dutch war. This was a conflict fought between England and the Dutch Republic for control over the seas and trade routes, where England tried to end the Dutch domination of world trade during a period of intense European commercial rivalry. The Four Days' Battle was one of the longest naval battles in history and was a Dutch victory.

The picture demonstrates every full moon in 2021 🌖

You may think that the stripes are not stacked correctly.
However, it depicts the change in the angular size of the full Moon as the year progresses, caused by the change in its distance from Calcutta, India, on planet Earth.

✔️ The inscription beside each bar shows the month, the name of the full moon, the distance to the moon in kilometers, and its angular size.

The last moments before the brain part excision...

The photo depicts a California prisoner, 1961, being prepared for a frontal lobotomy (amputation of the frontal lobe of the brain).

Such a procedure was often applied to people whose actions were considered immoral by society.

This is how the state tried to control problem groups such as racial minorities and homosexuals.

The most devastating magnetic storm of the 20th century: the Quebec Blackout

From March 5 to March 19, 1989, an active region passed across the Sun's disk, generating 11 X-ray flares and plasma emissions.

On March 13, the matter of two of the outbursts reached Earth and produced a powerful geomagnetic storm as a reminder to humans who rules the cosmic weather.

Self-driving delivery vehicles are operating on the U.S. roads

The startup, called Nuro, was founded by two former Google engineers in 2016. It is an autonomous grocery delivery system that was fully designed and tested in Arizona in just two years.

And now the company is receiving all the necessary permits from the Department of Transportation for mass use in several California counties.

The service will start with Toyota Priuses converted into autonomous vehicles, and later the company will switch to the R2 robot cars that are shown in the video.
