Lecture about Pulser (Neutron Star)

I attended a lecture about Pulser last Monday at Osaka Science Museum at Nakanoshima.
Pulser is a name for Neutron Star. Pulsar radiates special microwaves.
If you connect 2,000 TV-antennas, you can hear these microwaves by radio.

The sound of Pulser is like as the sound of tractor’s engine.
It beats steadily and constantly.
The fastest beat was 500 times in a second. And the slowest one needs 10 seconds for each pulse.

The lecture, which organized by British Council, was for common people.
About 50 people from 6-grade elementary school student to elderly were attended.

The speaker was Professor J. B. Burnel. She is the Dean of Science, University of BATH, England.
She found Pulser at 1967 as the first discoverer when she was a university student.

In those days, physicists found that sky was full of microwave radio noise.
When she found Pulser, many people said " That signal was what alien send to the earth".
Even people said the alien was named GREEN ALIEN. In that time, there was a cartoon, in which such named alien appeared.

But she observed two Pulser signals which came from opposite directions, so she believed there was no possibility of intelligence.
Because it was too difficult to believe 2 intellectual creatures send signals at same time.

One of my big surprises was the strength of the Pulser signals.
The several thousands Pulser signals observed in a whole year were no more strong than when you lift small sheet of paper.

And another big surprise was the weight of the Neutron Star.
If we pick up 1 cubic cm from Pulser and put it on a balance, its weight match with the weight of 6 billion people.

Hi, Kenn. This is Moring.
I'm sorry for late reply.
But you may be satisfing because Sakai-sansei wrote reply for your another writing.
I had hard time in this one week. Because I was making answer for English translation test.
Making answer was not going well, and I can't consetrate. Then I halted
Tadoku-reading until when I finished this. Now, I finished up this, and
I can restart Tadoku-reading.

Why does it need 2,000 TV-antennas? Because the length of wave or the weakness of wave?
May be the first one, I guess.

But why signals come from oppsite directions? Ether of two are
a signal that another one reflect against somewhere?

Less than 1g?

〉And another big surprise was the weight of the Neutron Star.

Uum. It's very heavy. I can't imagine.

Thank you for writing interesting story.
And congratulation that you already had read 3,500,000 words.
You read very fast.

Any way, Happy Reading!

Hi, Moring san.

〉But you may be satisfing because Sakai-sansei wrote reply for your another writing.

I just had done writing for him.
(I always sweat with writing in English.)

〉I had hard time in this one week. Because I was making answer for English translation test.

You should be a student arn't you? Do you major in English?

〉Making answer was not going well, and I can't consetrate. Then I halted

Welcome back!

Yes you are right, I believe.
The wave length of Pulser signals is about 3.7 meters.
In another words the frequency is 80 Mhz.
Usually the TV signals is between 100 and 200 Mhz, so called VHF band. (VHF stands for Very High Frequency)

No refrctions at all. That two signals came to the Earth incidentallty.

〉〉One of my big surprises was the strength of the Pulser signals.
〉〉The several thousands Pulser signals observed in a whole year were

Yes it is! Actually its enargy is approximately 10^-26Watts/m^2/Hz.
(^is powered. ex: 3^2=3*3=9)
But I'm not sure. So please don't ask me any more.

〉〉And another big surprise was the weight of the Neutron Star.

I completely agree withe you. But it is very interesting isn't it?

〉Thank you for writing interesting story.

Thank you very much! I really enjoy reading every day toward 4,000,000 words.

〉Any way, Happy Reading!

You also happy reading! See you!
