Who? Born…

 Biochemist Casimir Funk estadounidesnse of polish origin, born in Warsaw on February 23, 20, 1967.1884, New York and died in Albany on November

What did he do?

In 1910 he began researching the disease beriberi (affects peripheral nerves and finally, heart failure) . In 1911 he discovered through experiments that a substance found in rice husk, prevented the occurrence of beriberi. A substance that gave the name of “vitamins” (vita: life and amine: necessary for life). Funk concluded that only a small amount of that substance (1 mg) was sufficient to prevent the disease.

He published his findings in 1912 and in 1915 published the famous book called “vitamin”.

The Ice Cream Cone

The fist ice-cream cone was produced in New York in 1896 by Italo Marchiony, who had emigrated from Italy. He was granted a patent in December 1904. As with many great inventions, a similar creation was independently introduced – in 1904 by Charles Menches. He was selling ice cream – in dishes, like all ice-cream sellers at the time – at the St Louis World Fair. So many people were ordering ice-cream that he ran out of dishes. He looked around, and saw a Syrian man selling a Middle Eastern dessert called ‘Zalabia’, a wafer-like pastry sold with syrup. ‘Give me Zalabia’, cried Menches. He rolled up the Zalabia into a cone, scooped his ice-cream onto the top and the second ice-cream cone was born!

Newton, Sir Isaac (1642-1727) 

English natural philosopher, generally regarded as the most original and influential theorist in the history of science. Isaac Newton was born in the manor house of Woolsthorpe, near Grantham in Lincolnshire.

                                                             

Newton transformed the structure of physical science with his three laws of motion and the law of universal gravitation.

Newton's law of universal gravitation states that every point mass in the universe attracts every other point mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

Sigmund Freud

Sigmund Freud on 6 May 1856, was an Austrian neurologist who founded the psychoanalytic school of psychology.

Freud is best known for his theories of the unconscious mind and the defense mechanism of repression and for creating the clinical practice of psychoanalysis for curing psychopathology through dialogue between a patient and a psychoanalyst. Freud is also renowned for his redefinition of sexual desire as the primary motivational energy of human life, as well as his therapeutic techniques, including the use of free association, his theory of transference in the therapeutic relationship, and the interpretation of dreams as sources of insight into unconscious desires. He was also an early neurological researcher into cerebral palsy.

His father Jakob was 41, a wool merchant, and had two children by a previous marriage. His mother Amalié (née Nathansohn), the third wife of Jakob, was 21. He was the first of their eight children and owing to his precocious intellect, his parents favoured him over his siblings from the early stages of his childhood. Despite their poverty, they sacrificed everything to give him a proper education.

After planning to study law, Freud joined the medical faculty at University of Vienna to study under Darwinist Prof. Karl Claus. At that time, eel life history was still unknown. In search for their male sex organs, Freud spent four weeks at the Austrian zoological research station in Trieste, dissecting hundreds of eels without finding more than his predecessors had. In 1876, he published his first paper about "the testicles of eels" in the Mitteilungen der österreichischen Akademie der Wissenschaften, conceding that he could not solve the matter. Frustrated by the lack of success that would have gained him fame, Freud chose to change his course of study.

He studied too with Hermann von Helmholtz, one of the formulators of the first law of thermodynamics (conservation of energy).
