Great Thinkers: EratosthenesGreat Thinkers: Eratosthenes
Eratosthenes (c. 276 BC -- c.194 BC) was a Greek scholar nicknamed "Beta." This is because he was considered the second best in so many fields. Despite the dismissive nickname, Eratosthenes is still celebrated to this day for his significant contributions to math, astronomy, and geography. He is perhaps best known for measuring the circumference of the Earth, and for devising the "Sieve of Eratosthenes," a quick method for identifying prime numbers. -

"Be kind, O Bacchus, take this empty pot offered to thee by Xenophon, the sot, Who, giving this, gives all that he has got"

I so loved learning about rockets and getting into space that I continued to delve into physics in the form of a series of lectures by Professor Steven Pollack called Great Ideas of Classical Physics. Amazing stuff! He's good enough to avoid a lot of the mathematics and still give a loser like me a great sense of what it's all about. He recommended trying to figure out how one would figure out the circumference of the globe without today's modern technology. The dog and I tried, but we only got as far as the sun and something to do with shadows before we resorted to the Interweb where we learned all about Eratosthenes and his extraordinary skill and perceptiveness!

Congratulations to Velocity 2014 Motion Graphics & HDR Runner-up Chris Johnson-Stadley. Watch "Eratosthenes and the Circumference of the Earth", a charming animation voiced by Chris's son about the genius Greek natural philosopher Eratosthenes of Cyrene who over 2500 years ago successfully measured the circumference of the Earth. It's all beautifully explained in this short film so click play and check it out. The film was also shortlisted for the 2014 Guardian Witness Science Film Award. Produced with Adobe software. Well done Chris :) More info at scanprovideo.info

Sorry, can't find any Eratosthenes interviews.
Eratosthenes of Cyrene (Ancient Greek: Ἐρατοσθένης, IPA: [eratostʰénɛːs]; English /ɛrəˈtɒsθəniːz/; c. 276 BC – c. 195 BC) was a Greek mathematician, geographer, poet, athlete, astronomer, and music theorist.
He was the first person to use the word "geography" and invented the discipline of geography as we understand it. He invented a system of latitude and longitude.
He was the first person to calculate the circumference of the earth by using a measuring system using stades, or the length of stadiums during that time period (with remarkable accuracy). He was the first to calculate the tilt of the Earth's axis (also with remarkable accuracy). He may also have accurately calculated the distance from the earth to the sun and invented the leap day. He also created the first map of the world incorporating parallels and meridians within his cartographic depictions based on the available geographical knowledge of the era. In addition, Eratosthenes was the founder of scientific chronology; he endeavored to fix the dates of the chief literary and political events from the conquest of Troy.

Sorry, can't find any Carl Sagan interviews.
Carl Edward Sagan (
/ˈseɪɡɪn/; November 9, 1934 – December 20, 1996) was an American astronomer, astrophysicist, cosmologist, author, science popularizer, and science communicator in astronomy and natural sciences. He published more than 600 scientific papers and articles and was author, co-author or editor of more than 20 books. He advocated scientifically skeptical inquiry and the scientific method, pioneered exobiology and promoted the Search for Extra-Terrestrial Intelligence (SETI).
Sagan is known for his popular science books and for the award-winning 1980 television series Cosmos: A Personal Voyage, which he narrated and co-wrote. The book Cosmos was published to accompany the series. Sagan wrote the novel Contact, the basis for a 1997 film of the same name.
Carl Sagan was born in Brooklyn, New York, to a Ukrainian Jewish family. His father, Sam Sagan, was an immigrant garment worker from Kamenets-Podolsk, Ukraine; his mother, Rachel Molly Gruber, a housewife. Carl was named in honor of Rachel's biological mother, Chaiya Clara, in Sagan's words, "the mother she never knew." Sagan graduated from Rahway High School in Rahway, New Jersey, in 1951.
