Write a brief essay (in your own words, at least 300 words) describing the discovery, and what other explanations were considered at the time, and why pulsars were concluded to be spinning neutron stars, and did anyone predict them in advance?

Essay about pulsar

The highly magnetized rotating neutron star which emits a high beam of electromagnetic radiation from its magnetic poles is called as the pulsar. When the beam of emission is focused towards the earth they provide high emission of radiation. They produce radiations that range from a pulse of millisecond to pulse waves. The main source of energy for ultrahigh cosmic rays is the pulsars.

The periods that occur between the pulsars make them a very strong tool for astronomers for research purposes. They also confirm the existence of gravitational radiation. Joseph discovered a pulse for the first time in the binary system. The moment of inertia is very much high for neutron star. When a massive star is compressed during a supernova it collapses and forms a pulsar and then it emits a high amount of radiation.

The electric field is very strong along the poles resulting in the acceleration of electrons and protons in the star surface. The rotational power of the electric beam is converted into energy which is used to run the cosmic rays. This discovery of pulsar rays lead the astronomers a new level of discovery that they have not done before. The radiation of pulsar defines the radiation between the interstellar medium. The frequencies are measurable by using the formula.

The first pulse was discovered with 1.337 seconds. After the discovery of pulses the space science led to the discovery of new dimensions and they started discovering more. The neutron stars rotate rapidly due to the angular momentum the spinning neutron star loses its energy because of the periods and they spin rapidly.

The denser object in the universe is called as neutron stars and they are said to have a greater gravitational force than that of the earth and it is very much higher.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.

analyze the effectiveness of this excerpt. how does it function within the speech as a whole? how does the structure of the excerpt to convey the speech's purpose and key points? support your argument with evidence from the speech. (10 points)
