How they Invented Logarithms

Pretty geeky slide show about how people came up with the log function (and how it is that we got natural logs first).

[jeanious]

Seriously, all these years and somebody finally explains it in a sensible manner. Thank you!

Respect for people in the early years to do the brute force so no one else has to

This is the best mathematics video I've ever seen..It really makes me interested in mathematics and appreciate the beauty of it..For the first time in life I feel the urge to learn mathematics in depth..thanks for igniting my mind with this amazing video sir..keep making such videos.😁👍🏼

[pauligrossinoz]

Thank you!

This is the best intuitive explanation of logarithms that I have yet seen.

[joseestevao]

Finally understood how the natural logarithm was invented. Ingenious.

This will probably seem obvious to most but I think it might be useful to point out that the aim of applying a base as small as 1/10, 000 was to enable the log application to any number (well, almost). Perhaps it was just me not picking this up when listening. Thanks for sharing.

why no one taught me in this way in school

[yashitabawane]

Well, this tempted me to solve some of the complex logarithms.
THANK YOU VERRY MUCH!

Everytime I realize I forgot how to solve'em, I come back to this vid, and IT ALWAYS WORKS

I was intrigued by the word logarithms, so wanted to know how/why the word “logarithms” was used to describe this. The word “log” means a record, a ledger. “arithms” looks very much like the word arithmetic. It seems that the word {log-arithms} is just a joining of these two root words. Hence the word logarithms simply means a ledger/record/record of some number set.

Excellent presentation! Critical to the understanding of Logarithms

Did anybody else notice how the numbers on the right column are the pascal's triangle numbers? 2:30

[drapala]

great video, I appreciate your effort by doing this!

[truegrabbers]

He thought me in the best way of logarithms in my student Life

[trevorallen]

Tip: if you how many digits are behind the decimal form you can use it to tell you how many digits there at maximum when raiseing the power from the base except, for infinite repeating fractions or irrational numbers. You then have select finite digits of your desired. Example: if 1.0001 has 4 digits behind decimal then if i raise it to the power 2 then its 8 digits.
This is useful to keep track of your calucation because you will have a increase certain chance of discovering your missing or short/overshooting maximum digits behind decimals from vast large multiplication.

[kirstenwilliams]

Great little background history of logarithms!

[shankarjasti]

You cleared one of my life time questions.

[pronounjow]

I must be one of the only ones who didn't fully understand logarithms from this video, but I do like the presentation. Then again, I have a poor understanding of logarithms in general.

[nohaatef]

This is what I call a " good video ", Thank you

[RealSlopeDude]

GREAT video! I knew about Napier but not Jost. One person explained logarithms to me this way: A logarithm is the answer to the question: "What power do you raise this number (the base) to, to equal this other number?"
