Entrpreneurship


What does an entrepreneur have that other people don’t have?
They take greater risk than other people do and they work on their own rather than working with somebody else. 


Do you know anybody with that ambition? Who? What do they do?
Yes, my dad, he owns a business in the Philippines. He inherited the business from my grandfather. We have a store selling fishes and other He usually get stressed because he needs to gain profit 
The website admires 5 entrepreneurs. Which entrepreneur do you find the most interesting? Why?
How much does this course cost?
Would you be interested in this course if you received an 
entrepreneurship scholarship to take it?


Explain the difference:
Career           Job Entrepreneur
It is a chosen occupation or profession that is usually a long term. It is a regular activity in exchange of payment for the work and is usually a short term. a person who manages a business that takes greater financial risks than what is usual in order to do so in order to make profit. He works with himself rather than with someone else. 

Drones, Humans Greatest Weapons?

            The video implies that drones aren't the humans greatest weapons because even the chimpanzee's tool which is a "stick" can knock it down. It's funny how a chimpanzee defeated a human under the control of drones. What more if a human targets a drone using a weapon like missile? The missile will easily destroy it.  Drones still lack a feature to be considered as the greatest weapon.

DRONES

If we believe in freedom, democracy and justice, what is your opinion of Drones in war?


For me, drones should not be used in war for several reasons. First of all, war is a man to man conflict. It should not involve technology that could be controlled over a place not in the vicinity of the war. It is real bravery if you offer your own life to protect your country and people. Secondly, drones can harm the residents of the country more than the the war without using drones. With drones, great chances of number of deaths in the entire country is expected. Lastly, world peace would be harder to solve if drones is used as a future weapon since its a long range technology.

What are brominated flame retardants and why are they needed in computers?


Brominated flame retardants (BFRs) are organobromide compounds that have an inhibitory effect on the ignition of combustible organic materials. It is needed in computers because computers are the most widely used electronic technology in a long period of time. Using this, computers will have a reduced flammability. 

Who is the Greenest Computer Company?      a.   Dell?     b.  Apple

Dell is much a greener computer company than Apple.

Find out all the chemicals used in the making of a computer:

Solvents
Xylene(xylol, dimethylbenzene) - High fire hazard
Chlorinated Hydrocarbons
Glycols
The chip manufacturing industry is extremely complicated. Here are two of the most common ways workers are being exposed to chemicals.Solvents are widely used in electronics for cleansing, stripping, degreasing, operations, encapsulation, and as solders. These are activities which are defining the work day for many workers in Silicon Valley. Solvents are also the cause of a large portion of workplace hazards and exposure problems in the industry. The following have been chosen because of their frequency in the industry.
Aromatic Hydrocarbons
  • Benzene (benzol) - High fire hazard
  • 1,1,1-trichloroethane (methyl chloroform)
  • tetrachloroethane(1,1,2,2-tetrachlorethane)
  • ethylene glycol (glycol, EG, glycol alcohol)
  • methyl collosolve
Gases
The industry uses many potentially dangerous gases. Gases are found in ion implanters, diffusion furnaces, expitaxial reactors, etc. Gases are also used in quality control to detect flaws in electronic components. According to an industry journalist, many semiconductor diffusion furnaces are "all too likely to explode." So the exposure can be over a long period of time, or from a short blast.

How can St Pats students do something to recognize Earth Day and increase Awareness of E waste?

St Pats should have a seminar, symposium, or camps in which they are educated on what is e waste and what should we do aboout it.They should impliment a program in the school to prevent rapid accumulation of e waste. The action should start first in school and they could also help different communities about this.
