How Does Film ACTUALLY Work? (It's MAGIC)


For most people, film is obsolete.  I remember having a camera as a kid and there was something magical about cameras before technology came along.  

As best as I can recall, I didn't really bother with cameras from my college days onward.  It wasn't till sometime in my early 40's I got the most primitive digital camera possible, that only took 640x480 pictures, which matched some early computer monitor resolutions. I actually had fun with this camera despite the pretty low quality.  Eventually, mobile phones could take pictures even before smartphones.  

In 2008, I got an iPhone 3G which had a 2 megapixel camera.  
In 2010, I got an iPhone 4 which had a 5-megapixel camera.  
In 2012, I got an iPhone 5, which had an 8-megapixel camera.  I still own this phone.  The metal bands around the edge of this phone made it pretty tough, which allowed it to survive a pretty big accidental drop onto the pavement.  This will be relevant below...

In 2014, I got an iPhone 6+ which also has an 8-megapixel camera.  When I tried to participate in an Apple battery replacement program, something went wrong with the phone, so they gave me a free replacement which I still have.

Years later I got an iPhone 6S+ on a Black Friday sale.  It has a 12-megapixel camera.  Because the wi-fi died on in, I bought another one of these on another Black Friday to replace it, which is still my primary phone.  

Today I dropped my iPhone 6s+ and the screen cracked, but I managed to get it repaired the same day for $89.

How To Terraform Venus (Quickly)

https://www.youtube.com/watch?v=G-WO-z-QuWI

This seems unrealistic to me.

To terraform Venus, we should engineer a photosynthetic bacterium that can live in the upper atmosphere and consume CO2.  Not sure that is possible.

The early Earth was hell with an atmosphere of 42% CO2 and enough pressure to crush a man flat.  Photosynthetic bacteria changed the atmosphere.
