In another thread the concept of how many seconds in a year came up and it made me think of putting milestones of a human lifetime on a log scale. Units are seconds. Please feel free to amend or change or just make it better. Maybe an actual plot? What strikes me is most of life is in the last decade and a half from 10^8 to about 3x10^9.


UndefinedBirth
10^0First breath
10^1First cry
10^2First sleep
10^3First meal
10^4First ...
10^5eat, sleep....
10^6eat, sleep...
10^7crawl, walk, talk
10^8kid, teen, college, job, marriage
10^9grow old, die

Too many words. A picture (a log plot) is worth 10^3 words... :wink:

This is more a scale than a plot but yes it could be made with little icons representing the stages of life on a real log scale but that's a lot of work and I am not a graphics designer. It was more the idea than the implementation. Also, I looked but did not find a convenient log plotter online.

Perhaps changes take place over each period of fifteen years?

0-15: childhood
15-30 young adulthood
30-45 maturity
45-60 middle age
60-75 early old age
75-90 old age
90+ extreme old age

It was meant in the spirit of Phil Morrison's Powers of Ten but over time not distance.

This is how most people think of history. Fire is the center of time.

Doesn't this work in reverse as well? Last meal, last breath, last heartbeat?

And even in the middle? First meal today, first breath today, first heartbeat today.

Deep, man, deep.

Yes, but where do I put that on the scale?

Also, I could add a section from conception to birth.

In this time period are some of the most important milestones in one's life.
So say several biologists.
  • fertilization
  • gastrulation
  • body axis formation
  • etc.

Shouldn't that be on a log plot?

Nice, but seeing as how a partial picture may not contain enough useful information and multiple pictures just lead to confusion, I think it goes like *this;

desmos-graph (2).png


* function courtesy of prof. P.A.M. Dirac;

##Words(pics)=\frac{1}{a\sqrt{\pi}}e^{-\left(\frac{\operatorname{abs}\left(pics-1\right)}{a}\right)^{2}}\left\{pics≥0, a=0.000565\right\}##
