If you could please just state your opinions US & Global Economics questions?
1. Internet and reliable cars. Both require a ton of innovation and attention to detail, and only market system can motivate people to do that. 2. Efficiency b/c if costs of making something exceed the benefits of consuming it, that thing will not sell, and hence will not be made. Likewise, if benefits exceed costs, somebody can and will profit by making it. Freedom of choice. If you want something, and costs of making it are below your willingness to pay, it you will be able to get it. 3. Security is a public good, and is handled by establishing an organization that provides security and collects money from everybody it protects. Also known as government.
The Advantages And Disadvantages Of Global Positioning System?
An Advantages/Disadvantages discussion really only makes sense when you compare/contrast one thing to something else. Its not really clear what you want to compare/contrast to GPS. So let's make this a discussion of what the strengths and weaknesses of GPS are. Strengths: - GPS works in all weather - relatively low costs (compared to other navigation systems) - 100% coverage on the planet - accuracy can vary from millimeters to several meters depending on the technique that is used - because of its low cost, its relatively easy to integrate into other technologies (hence, the boom in the use of GPS in cell phones) - the system is maintained regularly by the US government (as compared to other navigations systems by other countries e.g. GLONASS) Weaknesses: - GPS satellite signals are weak (when compared to, say, cellular phone signals), so it doesn't work as well indoors, underwater, under trees, etc. - the highest accuracy requires line-of-sight from the receiver to the satellite, this is why GPS doesn't work very well in an urban environment - the US DoD (dept of defense) can, at any given time, deny users use of the system (i.e. they degrade/shut down the satellites) This list is not complete list but does highlight the major issues with GPS.
India got its own GPS system Navic. What is in it for Indian people?
As S.Ramakrishnan, Director of Vikram Sarabhai Space Centre said, “Geopolitical needs teach you that some countries can deny you the service in times of conflict. It’s also a way of arm twisting and a country should protect itself against that.”When Pakistani troops took positions in Kargil in 1999, one of the first things Indian military sought was GPS data for the region. The space-based navigation system maintained by the US government would have provided vital information, but the US denied it to India. From its Kargil experience India understood the inevitable need of navigation systems. Later in May 2006, the IRNSS’s R&D programme was approved.In 2012 US shut off it’s GPS satellites causing the BrahMos missile tests to fail. The GPS system couldn’t link onboard computers with hovering satellites eventually crippling its guidance system and keeping it from achieving mission objectives.Today, the Indian Space Research Organisation took the nation closer to its goal by accomplishing the task of developing the country’s own navigation system with the successful launch of IRNSS-1G, the last in the series of seven navigation satellites.With the constellation of satellites complete, India has joined the league of countries that has indigenous navigation system. The system will reduce the country’s dependency on US Global Positioning System. Apart from India, only a few other countries, including the US, the European Union, China and Russia have their own navigation systems in place.IRNSS will ensure C4ISR (Command, Control, Computers, Communications, Intelligence, Surveillance and Reconnaissance). Hence it will help in integrating data fusion and integration management system, radar, infrared, space based surveillance ensuring a high level accuracy in modern warfare.Most importantly IRNSS satellites are placed in High Earth Orbit (HEO) at a height of 35,786 kilometres. It has strategic importance when considering anti-satellite missiles. It makes IRNSS out of range of solid-fuelled intercontinental missiles and makes it a more challenging task for liquid-fuelled launch vehicles to reach this strategic height. At this height it can be easily traced by Indian government in order to take necessary actions as per the situation.http://greatgameindia.com/
Why is space exploration so important?
Initially, we were afraid the Russians would stake out the moon before us. The government's motive was fear. Now, most scientists agree that the space station is a waste of money and time, and lunar exploration has little more to offer. There is talk of sending people to Mars, and we could learn from that, and eventually, maybe, increase the longevity of mankind by setting up an outpost there (that's my speculation). However, more realistically, space exploration is MUCH cheaper and safer when sending robots instead of people. Another angle - I know people who went on to study what mankind could do to stop a meteor from destroying earth, and I think their research is probably in our best interest. Maybe we should think of it in terms of price per person. My calculations are that NASA costs us $62 per US citizen each year. We probably spend more on coffee...
What was the Great Depression?
What was it exactly? Why did it happen? What caused it? Who caused it What years were it? How was the economy affected? How were Mom & Pop stores affected? How were large companies affected? How were factories affected? How was farming operation affected? How were the rich affected? How was the middle class affected? How were the poor affected? If it never happened, how would life in America be like today? You don't have to answer all of the questions, just the ones you want.
