Well done. In 2018, I began a trip around the world eastbound from east US, and had to return beford reaching midpoint due to illness. In 2019, I set again, but was suggested by a friend to go westbound as I would be chasing the sun, thus less jetlag. My phone has an international plan, and when I was in Queenstown, NZ, my phone showed my local time and date, and my home time and date, and the date was off one day and 18 hrs behind. It was a great experience watching these two clocks difference as I moved west on my 7 week trip by air. I'm a sailor, and aviator, and use these methods very often to backup electronic navigation . On another trip from Sidney to east coast US, I arrived in the US 30 minutes after the time I left Sidney, on the same day. That was awesome. Great show.
Sir, a request. Your explanation is very lucid and clear but I couldn't understand the counting ahead part coz the black board was messy. Looking forward for more content.
Thank-you Sir..Really Expert .thanks for helping me..this video is really helpful and amazing...thanks..you cleared my doubts..regarding calculation of time .
Like Jaimy I am looking for the longitude problem video to follow on from these. How do I calculate longitude if I do not know the time? Really informative. Thank you.
And how do we find the star on the south ? north is easy, and you also explain this in your video, but were do we find the south star. This appears not to be so easy, or is it ?
If you live in the Southern Hemisphere, and you are familiar with the constellations, Sigma Octantis would be the star. But it's dim and pretty tough for most people to see with the naked eye. (One method we amateur astronomers use is "star hopping". ) I have read that the constellation Crux serves for navigation.
Great lecture. But ended with a cliff hanger. I was looking forward for part 3 but isn't! Oh the longitudinal problem.. guess i will have to google it.
