the application of scientific knowledge for practical purposes, especially in industry.
machinery and devices developed from scientific knowledge.

3rd + 4th slide: Technology as a way of knowing = internet

In fact cattle vision is dichromatic. This means that they’re essentially what would be described as ‘colour-blind’ in humans, so they don’t even see red as a bright colour. They merely perceive it as another variation in tone, like all the other variations.

14th 15th 16th slide : Space exploration, new planets, looking for asteroids
to look for life on other habitable planets
Giant asteroid heading for earth means the world is going to end – on 16 March 2880. An asteroid heading for Earth will cause destruction of biblical proportions, change the climate of the globe and devastate human life, scientists say – but not until 2880.
A lot of people think we should give up space exploration, largely due to cost (and it is expensive — NASA spends approximately 16 billion tax dollars each year). But It creates new technologies and products, as well as new jobs and businesses.
The cost for the Mercury, Gemini and Apollo programs was more than $25 billion at the time — more like $110 billion in today’s world. The ensuing U.S. space efforts have cost an additional $196 billion for the shuttle and $50 billion for the space station. NASA’s total inflation-adjusted costs have been more than $900 billion since its creation in 1958 through 2014 (more than $16 billion per year). Looking back, have we gotten our money’s worth from the investment? Should we spend huge amounts of money insteading of ending poverty and world hunger.
