Good morning, James Dray one that's near and dear to you..... and once a ticket is issued, there's no fixing anymore....so make sure you don't get one issued.

Good morning James - I have heard also of the Doppler effect.  We also remember his name.

Thank you very much, James, for sharing this interesting story.

Have a very special weekend.

Good morning again James. This one I knew. A good one. Have a terrific day.

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.

Well you have to have a good story to get out of that.

What can I say James

James,

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- all you had to do was say his last name and I knew what he was famous for!!!! Have a wonderful weekend. 

Hi James,  Thanks for sharing this interesting story.  Another amazing invention that has with held the test of time.

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.”
