Camera pixels.

Most of this blog is a copy & paste from A.I. output. I asked the questions in bold.

How many camera megapixels would you need to zoom into a photo that can show a man on the moon? 

To estimate the required camera resolution, we'll consider a few factors:

1. *Distance to the Moon*: The average distance from the Earth to the Moon is about 384,400 kilometers (238,900 miles).
2. *Desired image size*: Let's assume we want to capture an image of a person (about 1.7 meters or 5.6 feet tall) on the Moon's surface.
3. *Angular resolution*: We'll use the angular resolution of the human eye as a reference, which is around 200-250 pixels per degree.

Using these factors, we can calculate the required camera resolution:

Assuming a 35mm equivalent focal length, we can estimate the required resolution:

- For a 1.7-meter (5.6-foot) tall person on the Moon, we'd need an angular resolution of around 0.0002 degrees (or 0.012 arcseconds).
- Using the angular resolution of the human eye (200-250 pixels per degree), we can estimate the required resolution: 0.0002 degrees * 200-250 pixels/degree ≈ 40,000 - 50,000 pixels.

To capture an image of a person on the Moon, we'd need a camera with a resolution of at least:

- 40,000 - 50,000 pixels in a single dimension (e.g., 40,000 x 40,000 pixels).
- This translates to a total resolution of around 1.6 - 2.5 gigapixels.

In terms of megapixels, we can estimate:

- 1.6 - 2.5 gigapixels ≈ 1,600 - 2,500 megapixels.

So, to zoom into a photo and show a man on the Moon, you'd need a camera with an incredibly high resolution, likely in the range of 1,600 - 2,500 megapixels.

Keep in mind that this is a rough estimate and doesn't take into account other factors like camera sensor size, lens quality, and image processing capabilities. 


How many camera megapixels would you need to zoom into a photo that can show a man on Mars? 

To estimate the required camera resolution, we'll consider a few factors:

1. _Distance to Mars_: The average distance from Earth to Mars is about 225 million kilometers (139.8 million miles).
2. _Desired image size_: Let's assume we want to capture an image of a person (about 1.7 meters or 5.6 feet tall) on Mars' surface.
3. _Angular resolution_: We'll use the angular resolution of the human eye as a reference, which is around 200-250 pixels per degree.

Using these factors, we can calculate the required camera resolution:

Assuming a 35mm equivalent focal length, we can estimate the required resolution:

- For a 1.7-meter (5.6-foot) tall person on Mars, we'd need an angular resolution of around 0.000006 degrees (or 0.00036 arcseconds).
- Using the angular resolution of the human eye (200-250 pixels per degree), we can estimate the required resolution: 0.000006 degrees * 200-250 pixels/degree ≈ 1,200,000 - 1,500,000 pixels.

To capture an image of a person on Mars, we'd need a camera with a resolution of at least:

- 1,200,000 - 1,500,000 pixels in a single dimension (e.g., 1,200,000 x 1,200,000 pixels).
- This translates to a total resolution of around 1.44 - 1.8 terapixels.

In terms of megapixels, we can estimate:

- 1.44 - 1.8 terapixels ≈ 1,440,000 - 1,800,000 megapixels.

So, to zoom into a photo and show a man on Mars, you'd need a camera with an incredibly high resolution, likely in the range of 1.44 - 1.8 million megapixels.

Keep in mind that this is a rough estimate and doesn't take into account other factors like camera sensor size, lens quality, and image processing capabilities. 


The camera with the most megapixels today is the LSST camera which has 3200 megapixels.

The problem with a single African currency.

Preword: It's funny because one of the main reasons I found the courage to blog on African matters was due to a West African(?) gentleman who proposed the concept of a said "swal" & "zul" as a continental African currency in a blog. His boldness & conviction in his idea just captivated me & today I have to debunk this idea of his. But, hopefully, Africa sees why. African technologies & financial solutions Oh, Africa. We are so romantic; "United States of Africa", "Single African currency", "African unity", "Ubuntu"... all these fluffy, lovey-dovey concepts that will be ripped to shreds in the globalised world.  I debunked why a United States of Africa would likely collapse as soon as it sees the light of day. Today, I will debunk the concept of a "Single African currency" & explain why it would leave our enemies salivating.  I can't blame people who like stuff like United States of Africa...

A viable single African currency concept.

The original reason why I believe a single African currency would not work. Below is how we could attempt to make it work.  The many currencies of Africa. To prevent destabilization of the continent's economy, there could be two currencies: The Lami  for countries lying mostly north of the equator & the Ng'ombe  for countries mostly south of the equator. Both currencies would be independent with the Lami having it's bank & headquarters in Addis Ababa while the Ng'ombe could have it's bank & headquarters in Nairobi.  N.B.: Gabon, Congo-Brazzaville, DRC & Kenya would use the Ng'ombe currency while Uganda & Somalia would use the Lami currency.  North of equator = Lami  South of equator = Ng'ombe   More stable countries with higher GDP per capita could be first to use the new currencies i.e. Seychelles, Mauritius, Gabon, Botswana, Libya, Equatorial Guinea, South Africa, Algeria, Na...

What did King Shaka look like?

I've heard some people quoting from King Shaka's praises claiming that he was "like the sun" therefore light-skinned. But I'd like to ask how comparisons with the sun equate with being light-skinned? If anything, if King Shaka was light-skinned, they'd compare him to something terrestrial like the colour of a cow hide, wood or other object because very few extraterrestrial objects have the colour of any human skin. Even white people are called "ondlebe zikhanya ilanga" ('those who have translucent ears") & not  "abakhanya okwelanga" ("those who shine like the sun"). King Shaka's mother was from Elangeni & there is the Langa clan in KZN, all of them are black with many being exceptionally dark-skinned so I don't think the comparisons comparing King Shaka with the sun have anything to do with his complexion. Even the whites who first saw him & drew him wrote that he was dark & fairly tall. I also don...
