Logarithms are meaningless UNTIL you discover the slide rule. THEN it all makes sense and has a purpose.

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!

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.

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!!

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.

This reminds me, I don't remember exactly where I heard this, it was something on KZitem, 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

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.

Ideally if I were to compute these logarithms I would go for all the prime numbers first bc those numbers are not factorable thus, it makes calculation easier for large scale of numbers up to 100k to make myself log tables.

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.

According to your presentation, searching many websites and found finally myself the solution as example 10^x = 2 or 3/4 or some # w/o data on log tables. This piece is important to understand how the science community 16th or later centures had been resolved data on log tables. Trying exponential graph too but it is not close to get proper numbers. Again, thanks so much for it !

@aliasgharkhoyee9501 Say that you measure the displacement of a point on the ground sideways or Vertically. If the displacement is one, You give it a ranking of one, Even the displacement test is too. You give it a number of two, And so on. There is no reason for an earthquake Measured at 8 Being several times the orders of magnitude of an earthquake Deemed a seven.
