Arnulph Henry Reginald Mallock, a very important British scientist and inventor, was born on March 12, 1851, and passed away on June 26, 1933. He was known for designing scientific tools and doing many experiments. He was also a member of the Royal Society, a famous group for scientists.

Early Life and Learning

Arnulph Mallock was born in a place called Cheriton Bishop in Devon, England. His father, William Mallock, was a church leader there. Arnulph was taught at home for a while. From age 11 to 16, he went to a school in Harlow, Essex. After that, he had more private lessons before going to St Edmund's Hall, Oxford University.

Helping with Science and Engineering

For a few years, Arnulph helped his uncle, William Froude. His uncle was a naval architect, which means he designed ships. Together, they built the very first tank for testing ship models. This helped them see how ships would move in water.

After this, Arnulph worked for four months with another famous scientist, Lord Rayleigh. He helped Lord Rayleigh with his experiments.

Amazing Inventions and Projects

Arnulph Mallock was interested in many different things. He worked on a wide range of projects. Even the military and railway companies often asked for his help!

He designed special equipment to measure tiny movements. For example, he measured earth tremors caused by trains. He also measured small shifts in famous buildings like St Paul's Cathedral and several bridges.

He was part of a group called the Ordnance Committee. This meant he helped solve problems related to how weapons work and how things fly through the air.

Becoming a Royal Society Member

In 1903, Arnulph Mallock became a Fellow of the Royal Society. This is a big honor for scientists. When he was chosen, they said he was a great investigator and experimenter. They noted that he invented and improved many valuable scientific tools.

He wrote many important papers about his work. These included studies on how materials stretch, how cutting tools work, and how water flows. He also studied the properties of rubber and even how insects see!

In 1907, he wrote about a pattern of swirling fluid that scientists later called the "von Karman vortex street." He also served on the Council of the Royal Society from 1910 to 1912.

Family Life
