ULog Day 2:My first day in AGP 301 class(Exploration Geophysics)

I am writing about my first day in Geophysics class part 3,but it was an introductory class.it was an awesome class to attend because I learnt about new things,how the gravitational field works,and some which I am aware of.
The class started at 9:00 a.m,firstly I got to see my friends once again,we just resume a 4 months break which was suppose to be a month break because of the hike in our school Fee in Adekule Ajasin university,initially we were paying #26,000 naira per session which was increased to #200,000 naira...it was a hell of protest to bring it to #100,000 naira by we the students and our parents because the economy was unbearable, but we thank God we fought for our right, at least we were heard..
So,the class was quite at first when the lecturer came in,it was a new lecturer,Dr. M.B. Aminu,department of Geophysics of Adekunle Ajasin University. Firstly he introduced himself,but everyone was nervous, he them wrote AGP 301 on the marker board, he gave us the course outline and the lecture went on Gravitational Force.He stated the Newtons law of gravity,which states that

The force of attraction between two masses M1 and M2 is proportional to the product of the masses and inversely proportional to the square of the separation between their centers.

Which is denoted by
F=¥M1M2/r^2
¥=Gravitational constant=6.67×10^-11 NM^2/kg2.

The lecture continued, and the lecturer deviated from AGP to history,he talked about Africans how they first started the slave trade,how they went to Spain to take slaves and so on..he then asked us Who discovered America? But I was confused at first but I do know who discovered the sea route to America, which was Christopher Columbus,I answered and he said I was right..so its great to know the history sometimes.. I was glad and he recommended a book for us which was titled "They came before Columbus" by Ivan van sertima
Now he switched back to AGP, he continued the class and ended it with

gravitational acceleration

As he was about to leave,he also recommended a book from the Library,

fundamental of Geophysics by William lowrie

He marked the attendance and left the class and he said we will be discussing Geophysical exploration in the next class...wow,it was a great class because of the interaction between the lecturer and the students. So everyone dispersed and went for the next lecture.
