The explorer had some obstacles to go through before he could reach his destination.
Low-frequency signals have longer wavelengths, which allows them to diffract around obstacles and follow the curvature of the Earth. However, their ability to carry information is limited by noise and interference, which can degrade the signal over long distances. Additionally, low frequencies tend to be absorbed more by the atmosphere and other media, leading to significant attenuation as the distance increases. Consequently, while they can travel farther than high frequencies in some environments, their effectiveness in carrying clear information diminishes over long distances.
Some of them are long and some are short.

Inventor and engineer Elijah McCoy died in Detroit in 1929. He was 86, and he suffered from dementia and from injuries he sustained in an auto accident in which his second wife died. Though the accident was some seven years past, it appears complications lingered.
some people say March 27,1843,some say May 2,1843, and some say May 2,1844.

Elijah McCoy is a famous African American inventor. His first major invention was a lubrication for oiling the engines of locomotives and steamboats which he patented in July of 1872. He has obtained about 57 patents, all relating to lubricants, but also invented the folding ironing board and the lawn sprinkler. He is also associated with the saying, "the real McCoy", meaning, "the real thing", because railroad workers would inquire if their locomotive was fitted with "the real McCoy" rather than some inferior copy.
it is unknown but we do know from age 3 till age 15 he lived in detroit and did attend some school in that time period.
so much time is wasted by trying to be better than others. Dream the impossible because dreams do come true. I am not a star, a star is nothing but a ball of gas. Going against the grain of society is the greatest thing in the world.
There are many African American people that are not well known. Elijah McCoy, Lewis Latimer, Jan Ernst Matzeliger, and Granville T. Woods were all famous for their inventions.
