Lenght, Mass, and Time

Length

Yard – In A.D. 1120, yard is measure from the standard length of the kings tip nose to the end of his outreached arm (King Louis XIV).

Meter was originally defined as one ten-millionth of the distance from the equator to the North Pole (1791).

Meter was defined by an atomic standard, in terms of the wavelength of the orange- red light emitted by atoms of Krypton (86Kr) in a glow discharge tube; one meter was defined as 1650763.73 of these wavelengths (1960).

Meter was redefined as the distance traveled by light in vacuum during a time of 1/ 299792458 second.

Mass

The MKS unit of mass is Kilogram. Kilogram (Kg) is defined as the mass of a specific platinum-iridium alloy cylinder kept at the International Bureau of Weights and Measures at Serves, France (1887).

Time

The unit of time was based on a certain fraction of the mean solar day, the average time interval between successive arrivals of the sun at its highest point in the sky (1960).

In 1967, the second/s is redefined as 9192631770 times the period of vibration of radiation from the cesium atom (Period is the time interval needed for one complete vibration).

Who are my superfriends?

First of all if you click my button you are the superfriend.

This means that you are my very supportive friend.
And I really treasure you.
Thank you very much for all the support and help.

Investment TIPS

Most of the people in stocks are not saying anything about the companies failure but instead their strength are being introduce in an investors like saying the big volume of the stock, the close price of the stocks well this is not the correct manner in investment. Here are some of the tips to be successful Investors.

1. Checked the company's profile. The companies profile will lead you on how the company succeeds in their business and also you can see their failure but you have to be careful because some company hides it. To be more safe go to their competitive firm then the other company will say their weakness.

2. Checked their chart for 5 to 10 years. The Chart tells you on how the company performance during the year. If the charts went down go and run away. And if the chart is going up then continue on checking.

3. Get a copy of their financial statement. Before investing get a copy of the company’s financial statement. Don’t invest yet! Tell the company that you going to study first if you going to invest or not tell them the truth that you are going to checked their performance.

4. Compute their performance. The performance can be computed using the formulas on finance book. You can use foundation of finance to get the performance.

Another tip if you don’t like to compute check their assets and liabilities but be careful because the company financial statements are somewhat manipulated but if you compute it thoroughly they can not escape.

Go Rooseveltians!!!

Proud to be Rooseveltian

I am a product of Roosevelt College San Mateo when I was in High School then when I took up my Masters of Arts in Education major in Physics degree in Roosevelt College Cainta. Actually I couldn’t imagine how I finished my masters because most of our professors are strict especially the couple Dr. Casambre’s. But anyway I offer this article to them because they mold me a lot in pursuing my career in fact I could forget them especially the male Dr. Casambre. Most of my professors in Roosevelt were from the Alumnie of University of the Philippines that why they are very strict especially in terms of requirement and performance. They often checked every details of your work. One of the most important thing that I often remember with the male Dr. Casambre was when he enters our room he always bring a picture and ask the class to describe what we can see on the picture and tell him what story is behind on it. At first I couldn’t see any relevance of studying English in my Physics but after finishing it. I learned that it will lead me to another horizon of my career. Learning English was so difficult especially when you are good in Mathematics. This is the very common saying’s here in the Philippines. But actually English is very enjoying because you can read lots of article and relate some articles on the real life story.

Another professor that I want to acknowledge is Dr. Carmelita U. Cruz, she is my mentor in Statistics and Physics, she is very kind and approachable professor that I ever met in my masters. She is also a very good teacher most of the statistics problem can solve by this professor in fact she has lots of published books in the Philippines. She enlightened me to be more of statistics. Actually every time I teaching statistics and economics I remember her because she is just like an outstanding teacher. I am now having my new journey in life because of this passed experienced that I learned from them. My heart still on my Roosevelt my alma mater.

Roosevelt College my beloved school

Willing to grow

We learned to show

To thee I pledge my loyalty

I am proud to be Rooseveltian.

Mabuhay ang Roosevelt!!!
