Johannes ( Hans ) Willhelm Geiger and Walther Muller
Hans Geiger invented the Geiger counter, a device used to detect and measure ionizing radiation. It works by counting the number of ionizing radiation particles that interact with a gas-filled detector, producing an audible click for each particle detected.
The Geiger counter was invented to detect and measure ionizing radiation, specifically alpha, beta, and gamma radiation. It was designed to provide a simple and portable device for monitoring radiation levels in various environments to ensure safety and protect against harmful radiation exposure.
Geiger counter was invented by the Hans Geiger in 1908.
Lasers were invented in 1960. The word laser stands for "Light Amplification by Stimulated Emission of Radiation." It refers to a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation.
The radiation dosimeter was invented by Werner Forssmann and Burchard B. Harned in the 1920s. They developed the first wearable dosimeter to measure radiation exposure in workers.
abacus
The first mechanical counting device was invented by Blaise Pascal in 1642. It was primarily used as an adding machine. It could add and subtract two numbers.

Pre-historic humanoids who discovered that they all had five finger (including thumb) on each hand.
The first modern-style electronic calculator was invented in the 1960s. The first counting device, an abacus, was invented in Egypt in about 2000 BCE. The mechanical calculator was developed in the 17th century.
The last prophet HAZRAT MUHAMMAD MUSTAFA (PEACE BE UPON HIM) INVENTED COUNTING
Geiger counter was invented by the Hans Geiger in 1908.
The pyranometer was invented by Angström in 1893. It is a device used to measure solar radiation, specifically the direct and diffuse components of sunlight.
Lasers were invented in 1960. The word laser stands for "Light Amplification by Stimulated Emission of Radiation." It refers to a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation.
