The Naming of The Tropics

The Naming of The Tropics
  • The Tropic of Cancer. It was so named 2000 years ago because the sun was positioned in the Cancer constellation during the June solstice.
  • The Tropic of Capricorn. It was so named at the time because the sun was in the constellation Capricorn during the December solstice.

The sun is no longer in those constellations at that time of year. The sun is now in Taurus at the June solstice, and in Sagittarius at the December solstice.



Why the Tropics Are Important

  • The Tropics are places within the hemisphere where the sun can be directly overhead.
  • This was essential for ancient travelers who used the sun and stars to guide their way.
  • The Tropic of Capricorn can be found at latitude 23.5 degrees south, and the Tropic of Cancer at 23.5 degrees north.


The Major Circles of Latitude

Latitude and longitude are used as addresses for every part of the world. On maps, latitude lines are horizontal, and longitude lines are vertical.

To define boundaries between countries that lack distinctive geographic borders, like mountain ranges or deserts, arcs of latitude are used. There are five significant latitude circles: Arctic Circle, Tropic of Cancer, Equator, Tropic of Capricorn, and Antarctic Circle.


Living in the Torrid Zone

The geographical zone between the Tropic of Cancer and the Tropic of Capricorn is known as the Torrid Zone - also commonly known as the tropics.

The tropics have a moist climate and lush green vegetation. It is warm to hot year-round. Some areas in the tropics such as the Sahara desert or Australian outback are defined as "dry".



Wealth Is A Relative Term

Wealth Is A Relative Term

The definition of wealth is personal. It may mean something different to everyone.

How Much You Need to Become Wealthy In Dollars

According to a Modern Wealth Index Survey, the amount needed to be comfortable in America is $1.4 million. To be wealthy, you'll need a net worth of $2.4 million.

An average pre-tax yearly salary of $389,436 is needed to be in the top 1%, although it varies by state.

Buying Time

We all, rich or poor, have the same 24 hours in a day. But we can use our money to buy more time. For example, by eating out, you don't have to decide what to cook, shop for ingredients, cook, and clean it all up.

If you can carve out more time for yourself, you can use it in other ways that will improve your life. You can start a side hustle, exercise, read, or spend time with family and friends.

The northern lights, or aurora borealis

The northern lights, or aurora borealis

The magnetic fields of the sun distort and twist as the Earth rotates on its axis. When these fields become knotted together, they create sunspots. Usually, these sunspots occur in pairs.


Auroras on other worlds

Auroras also occur on planets such as Jupiter, Saturn, Uranus, and Neptune. These gas giants have thick atmospheres and strong magnetic fields. These auroras are a little different from Earth's as they are formed under different conditions.

Venus has an aurora generated by its magnetotail. Mars experiences local auroras due to magnetic fields in the crust. There are also northern hemisphere auroras caused by particles hitting the Maritan atmosphere.

Cycles and particles

Northern lights occur roughly every eleven years. Record-keeping of the sun's activity began in 1749. Since then, there have been 22 full cycles.

Particles ejected from the sun travel 93 million miles toward Earth before they are drawn toward the magnetic north and south poles. As the particles move through the Earth's magnetic shield, they mix with the oxygen, nitrogen, and other elements that result in the display of lights.

The frames we use to see the world

The frames we create for what we experience both inform and limit the way we think.  And most of the time we are not aware of the frames we are using.

Being able to question and shift your frame of reference is an important key to enhancing your imagination because it reveals completely different insights.

Reframing problems

It takes effort, attention, and practice to see the world around you in a brand-new light.

You can practice reframing by physically or mentally changing your point of view, by seeing the world from others’ perspectives, and by asking questions that begin with “why.”
