But that's not more that two sexes. It's the same number or less. A hermaphrodite isn't a third sex, it's two sexes side by side and a sexless cellular organism has exactly one sex.
The distinction male/female is usually determined by measuring the size of the gametes. Female gametes are the bigger ones (e. g. ovum) and male gametes are the smaller ones (e. g. spermatozoon). There are organisms where the gametes of both sexes have the same size. So technically they have two sexes but don't fit the categories male and female.
when you realize the average reading level of the US is at a 7th grade level and 20% read below a third grade level it explains why companies require degrees.
Ouch. I didn't know it is so bad. How could the people allow that? Why is nobody on the street and marching for more education?
Let's say the European goes to work at 8 o'clock UTC. The American in this example goes to work 6 hours later at 14 o'clock UTC. Both now exactly when the other one is in office. Time zones aren't needed here.
Time zones are an invention to keep the zero hour (for hour counting) at about the same local time - midnight. Midnight was easier to determine that UTC (or GMT). A peasant could do it in a day without the help of expensive tools everywhere on Earth. As a matter of fact almost each city in medieval times had its own local time. To get that sorted out they where clustered into time zones.
In Old Egypt and in the medieval times they counted 12 day hours from sunrise to sundown and another 12 night hours from sundown to sunrise. A lot of systems do/did that because one tracked the sun and the other tracked the moon and the stars. It's more like as 12 + 12 hours system instead of a 24 hours system.
In the Babylonian system the day had 24 hours, beginning at sunrise. The name has nothing to do with the ancient Babylonians though. 🤷♂️
The Italian system was the same as the Babylonian system but began counting at sundown. This is also the case in the Hebrew and Islamic calendar. Btw that's the reason why Christmas night starts at the 24th of December in some countries (like Germany) and the 25th of December in other countries (like USA). The former converted from the old date/time system to the modern done while the later just went 'Nah! We'll do what the Bible says.'
The ancient Babylonians had danna, double hours. Hence a day had 6 day and 6 night dannas.
Then there are still used 12 hour clock dividing the day in ante meridiem (before midday) and post meridiem (after midday). It is mainly used in Britain and countries that were ruled by the British Empire.
There's the current 24 hour clock starting and ending at midnight.
There is the Julian Day where the counting -again- starts at sunrise. It is still used(!) in astronomy.
There is Rammesses II's hour calendar where the number of day and night hours changed depending on the month. June-July had 18 day and 6 night hours. December-January had 6 day and 18 night hours. Why does a country near the equator need 18 day or night hours? It's not that the day and night length change that much during the seasons. 🤷♂️
The Chinese calendar changed several times. Each day started and ended at midnight (like today) and initially was divided in 100 ke (1 ke = 14.4 minutes). Later that number changed to 120 (12 * 10), 108 (because 12 * 9) and 96 (12 * 8). When they also introduced double hours, ke became 15 minutes long. The double hours started counting at 23:00.
And many more.
Also it isn’t a bad idea to work less hours in winter so you can experience the sun at all.
In the times before the light bulb work could only be done during the day. Candles made from beewax were too expensive for the peasants. If they used candles instead of kindling they were made from tallow and created a lot of smut and didn't gave much light. That made them a bit unpopular. I wonder why? 👤
At least in my country work days were divided in morning, midday, afternoon and night. You worked your field during the morning, went to market at midday, did handyman work and chores during afternoon and slept during night time.
I'm not sure if #ebooks mirrors Libgen. I wouldn't be surprised if they copy from each other.
I have allergies against ads, countdowns, etc. The interweb is polluted with that stuff and so are most piracy sites.
I find irc to be much easier to use than the alternatives. Just a click to start hexchat and then it auto-connects to the right server and auto-joins the right channel. All within seconds. I even get my animes from irc like I did in 2005. 😁
