Christian Andreas

Managing Real Estate Broker with Fathom Realty PB00068179

Christian Andreas was born in Salzburg, Austria back in 1803. After graduating from high school, he studied mathematics and physics at the Imperial-Royal Polytechnic Institute in Salzburg. In 1835, he worked for the Prague Polytechnic University in Prague. He published an article on the observed frequency of a sound wave and the relative speed of the source.

Due to the Hungarian Revolution of 1848, he fled to Vienna, where he was appointed head of the Institute for Experimental Physics at the University of Vienna. He died in 1853, he was 49.

What you may not know about Christian Andreas Doppler is that his theory and mathematical formula is still in use to this day. When I was in law enforcement we called the radar unit “The Doppler”, so when you get stopped for speeding you can thank Christian.

Your day is worthwhile when you make someone smile, so give the free gift of a smile today

Good morning James,

You have jogged the memory from high school days and the instrument of law enforcement is familiar to me!

Make yourself an astonishing day.

I certainly had heard of the Doppler radar, the weather people talk about it, and just the other day, about the Highway Patrol.  I did see them using their radar.  A

Hello James - I knew of "doppler" but the man behind the name.  Thank you for sharing this information.  You continue to help fill in some of the (many) "blanks" that exist for me with your mini-biographies.

Hmm, I don't recall his theory and formula from my days of studying mathematics, but then again, that was a very long time ago, haha.

It is amazing how much stuff we use was invented so long ago. I never knew you were in law enforcement. You learn something every day, today I learnt two things at least.

Hi James, certainly have heard of the Doppler, but never who was behind it. Had no clue it was named after the inventor.

Thank you for sharing about Christian Andreas Doppler-and that his theory and mathematical formula is still in use. We can "thank" him for those police radar guns, aka “The Dopplers.”
