Change in colors over the years

The Statue of Liberty and the Color Change of Copper Over Time

When installed in 1886, the surface of the Statue of Liberty consisted of new copper sheets with a bright orange-gold color.

Over time, the copper reacts with atmospheric elements such as oxygen, carbon dioxide, and moisture, resulting in a gradual oxidation process.
After several months, the surface begins to darken into a bronze tone. After about one year, it turns dark brown, approaching black, due to the formation of copper oxide layers.

After approximately five years, a layer of copper carbonate-known as patina-starts to develop, and the green color gradually appears. By the tenth year, this coating covers most of the surface. After about twenty years, the distinctive blue-green patina is fully formed.
This final layer serves as a protective barrier that reduces further corrosion of the metal, helping to preserve the statue for more than a century.

[Request] Which day would be the exact point where more than half of the population celebrated their birthday in a year? I don't mean the midpoint of the year (July 2, 12:00 PM), I mean accounting for the late summer birth spike (more people being born in the later half of the year)

[Self] Made an approximate calculation on how loud the Greybeards were when they called Last Dragonborn to High Hrothgar. Tell me where I made mistakes.

If you ask why the map of Britain is there that's how large the map of Daggerfall is, thus it¨s probably the most likely canonical size of this country in lore.

I used megaphone as I think that the noise with which Greybeards can be approximately heard in Whiterun.

[Request] Will this couch fit down the hall and into the guest room?

I used to be so much better at math but stopped riding that bicycle long ago.

I hate that I have to post this, but here we go.

Trying to purchase a non-returnable custom color couch.

It has to go down a 36” wide hallway with a 96” ceiling. Hallway is 140” to “couch room” which is a right angle left turn entrance from the hall.

Couch room has a 29” x 81” entrance with nothing in the way once it’s through.

Directly across from the couch room is a linen closet with a 23” x 81” door that could potentially be used to help lean couch back further.

What I’ve gotten to is that the couch should be standing up length side 79” and arms in first. 24.75” height to arms and 32.25” height to back of couch after removing the legs (confirmed). If couch can be leaned back far enough and worked at an angle into the room I think it could be close but I just don’t know.
