A simple pendulum is composed of a weight, or bob,
hanging freely from the end of a string or bar. Gravity pulls
the bob in a downward arc, causing it to swing. There are
different types of pendulum. Foucault pendulum swings in
two dimensions is a type of simple pendulum, which
demonstrates the rotation of the earth. Once the Foucault
pendulum is set in motion, its swing will tend to rotate
clockwise in a circle over the course of about a day and a
half. Double pendulum, which is called a chaotic
pendulum, consists of two simple pendulums, one
suspended from the other. Double pendulums are used
primarily in mathematical simulations. Conical pendulum,
which was studied by Robert Hooke, is used to analyze the
planets’ orbital motions.

Asteroids play a vital role in the future of humanity, and
scientists have shown great attention to them. Asteroids are
important for three reasons. The first and most important
reason is that they may have been sent by aliens; such as the
Oumuamua asteroid, which has been the subject of much
debate. The second reason is the possibility that human life
continues after the destruction of the planet with the help of
asteroids (of course it is not possible to live on asteroids,
but it is possible with our knowledge about them, we may
be able to reach other planets that are also in the solar
system). The third reason is that asteroids can collide with
the earth like meteorites and destroy it.

In general, heat is transferred through three methods of
conduction, radiation and convection. The heat of the flame
melts the paraffin of the candle due to its conduction.
Melted paraffin rises from the candle wick due to its
capillary properties. On the other hand, hot air rises around
the flame. The volume of hot air is more than the volume of
cold air and its density is less it is from the density of cold
air. When hot air loses temperature, it cools down and cold
air because of more density is being pulled down by
gravity, and this heat transfer current continues, which is
called convection. Radiation is another type of heat
transfer that takes place through electromagnetic waves.

Congenital or acquired physical disabilities have
negatively affected people’s lives for centuries and have
caused them to encounter various difficulties. Such
physical disabilities affect large number of people when
their loved ones who help them are considered as well.
There are many different definitions of disability in the
literature due to the difficulty of defining it. However,
considering the common points of these definitions,
disability can be explained as “the need for additional
support due to various disabilities, congenital or acquired
as a result of different reasons, that negatively affect one’s
life” (Yumuşak, 2014).

Kapok is a type of fiber obtained from plant seed such as
cotton. This tree (Ceiba pentandra), whose homeland of the
Kapok tree is the tropics of America and the West Indies, 2
today, mainly Java, and some Asian countries such as the
Philippines, Malaysia and Sri Lanka. It is widely cultivated
to obtain fiber in their countries. In general, the regions 15
degrees north and south of the equator are the regions
where good kapok products are obtained.

The macromolecules formed by many small molecules
bound together are called polymers. Polymers are formed
by the chemical bond that monomers form as a result of the
reaction under suitable conditions. Polymers are studied as
natural and artificial. In the natural polymers section,
proteins, cellulose, chitin, starch, RNA and DNA; In the
artificial polymers section, there are synthetic rubber, PVC,
silicone, nylon and plastics (Saçak, 1998). Some artificial
polymers are widely used in packaging (Sarıgül, 2018).

In order to fully understand the characteristics of the
periodic structure of photonics crystals formed by
dielectric and superconductors, it is beneficial and crucial
to examine the foundations of photonics crystals. Based on
these foundations, the analysis of band gaps can also be
carried out and examined more deeply

The emission of energy in space in the form of waves or
particles is called “radiation”. Radiation is classified as
ionizing and non-ionizing radiation (Bor, 2015). The
ionizing radiation is the radiation that forms ion pairs by
removing electrons from the orbits of the atom it
encounters. The ionizing radiation is divided into two;
Particle-type radiation: They are very fast-moving
particles with specific mass and energy.
