Q & A

What are the main branches of science mentioned in the video?

The main branches of science mentioned are physics, biology, and chemistry.

What is the difference between a 'chemist' in the UK and other countries?

In the UK, a 'chemist' refers to a pharmacist, someone who prepares and sells medicines. In other countries, a chemist typically refers to a scientist working in the field of chemistry.

What do scientists do to develop and test theories?

Scientists conduct research, experiments, and tests to either prove or discard their theories.

What is the significance of 'breakthroughs' in science?

Breakthroughs are major discoveries that can change the way people live. For example, the discovery of penicillin led to antibiotics, and semiconductors enabled modern electronics.

What is the difference between a machine and a vehicle?

A machine is a piece of equipment with moving parts that works on mechanical power to perform a specific task, while a vehicle is a type of machine used for transportation. All vehicles are machines, but not all machines are vehicles.

How do 'devices' and 'appliances' differ in technology?

A device is a general term for any piece of equipment, especially electronic, while an appliance is a device designed for a specific function, usually for household use, like a toaster or a blender.

What does the term 'cutting-edge' technology mean?

Cutting-edge technology refers to the latest, most advanced technology available, often considered state-of-the-art.

What is the main difference between digital and analog technology?

Digital technology stores and processes data in the form of digital signals, while analog technology relies on a continuous form of data storage and processing.

What is artificial intelligence (AI), according to the video?

Artificial intelligence (AI) is the ability of a computer or robot to perform tasks that typically require human intelligence, such as problem-solving or decision-making.

Why is there concern about the future impact of AI on jobs?

There is concern that AI may replace many human jobs, which could lead to societal challenges as machines take over tasks that were once performed by people.
