World Mosquito Day is celebrated every year on 20th August to raise awareness about the importance of mosquito control. On this day in 1897, Ronald Ross discovered that anopheles mosquitoes are responsible for malaria. 1/3

On this day in 1894, Sir William Ramsay and Lord Rayleigh discovered the element Argon. Argon was the first discovered noble gas. It is an inert, colorless and odorless gas, which emits a distinctive violet glow when ionized. 1/3

[Spectra @Spectra_sci]

It is the most abundant noble gas and makes up approximately 0.94% of the Earth's atmosphere. Argon has a wide range of uses. It is found in lasers, lightbulbs, rocket propellant and fluorescent tubes. 2/3

Today marks the birthday of a British mathematician and physicist, Roger Penrose. He is best known for his work in mathematical physics, especially for his contributions to general relativity. He attended University College, London, and graduated with a degree in mathematics. 1/3

[Spectra @Spectra_sci]

In 1957, Roger Penrose earned his doctoral degree in algebraic geometry from the University of Cambridge. His work along with Stephan Hawking on the properties of black holes revolutionized our understanding of the nature of the universe. 2/3

Carl David Anderson discovered the positron on 2 August, 1932. A positron is the antiparticle of an electron and has the same mass and spin of an electron. This antiparticle was predicted by Paul Dirac in 1931. 1/3

Today marks the death anniversary of Maryam Mirzakhani, a mathematician and professor of mathematics at Stanford University. Mirzakhani established herself as a prominent figure in her subject area, having done her research on various topics.

[Spectra @Spectra_sci]

It was due to her research that in 2005, she was honored in Popular Science's fourth annual "Brilliant 10" in which she was acknowledged as one of the top ten young minds who have pushed their fields in innovative directions.
