Regarding 0:45, following John Napier’s invention of logarithm tables in 1614, William Oughtred in 1622 invented the slide rule which was a calculating instrument utilizing logarithms to conveniently perform multiplication and division of numbers.

I was so bored studying Logarithm and then felt exhorted to know the practical uses of it. Your depiction of the history behind it really made me enthusiastic. Thanks!
@samyuktg4413
Thank you for this, really helpful. One of the few resources that actually explain logarithms in a practical sense rather than just dumping a couple of mathematical properties.

“Very Small numbers are made easier to deal with.. Thanks to Logarithms” 👍👍 This video really logs a rhythm :)
@zaproud
this video is so underrated , this is one of the most informative videos about LOG EXPLANATION that I have seen on youtube this should be recommended to every student
@stevendeacy7399
HNC in electrical and electronic engineering , which of course uses logs algebra with many brackets . This video is an absolute revelation . Thank you .

I know how much 14x12 is, but it's not necessary to use an antilog table in conjunction with logarithms to find the answer. I know all the logs to three decimal places up to 100. If I add log 14 to log 12, I get 2.225. The characteristic of 2 tells me that I have a three-digit answer. If log 16 is about 1.204, then log 160 is about 2.204. And if log 17 is about 1.230, then log 170 is about 2.230. 2.225 is about 4/5 of the way between log 160 and log 170, so the answer must be about 4/5 of the way between 160 and 170. Therefore, the answer is 168. The unit digits of 14 and 12, when multiplied together, give me a units digit of 8. Logarithms involve some rounding errors, because the exponents involved are irrational numbers, but small errors can be dealt with by common-sense methods such as the one described above. Some mental calculators of the past used logarithms as shortcuts to determine the answers to difficult problems.

Just as a warning if you use this in class: when talking about water's pH: the audio says log -7 instead of -log 7 . It's great to check if students are understanding! Thank you for the video!!
@reineh3477
I learned logarithms many years ago and felt I had to refresh my memory. This video was so good I'm going to recommend it to my friends.
@hariharsahu4803
I loved the background music... So muchhhh soothing 🙂
@888ussama
This just solved the most outstanding question from my history . Thanks
@marlonbryanmunoznunez3179
Best explanation I've found on this subject online. Great work. Subscribed!
@sravankumarjr
whatever the Video add History (timeline & scientists) ,the sound edit and examples just simple and effective 🤗
@Vampire-Catgirl
This reminds me, I don't remember exactly where I heard this, it was something on YouTube, but young kids just starting math tend to also think logarithmically in terms of numbers. If you ask a kid what half of 16 is, they're far more likely to say 4 then they are 8, because logarithmically 4 is halfway between 1 and 16
@studyguru5892
Fantastic work and fantastic way of explaining
@glynnwright1699
Slide rules were often affectionately called 'guessing sticks' by engineers and were still widely used until the early 1970s when the first (very expensive) electronic scientific calculators were produced by manufacturers such as Hewlett Packard.
@arsalansakhawat356
Brilliant
@adr420
Thanks for giving your time....

This was well done. Thanks for the work you put into this
