Technology is often defined as the application of scientific knowledge for practical purposes. This definition emphasizes the role of science in the development of new technologies.

Science is the foundation of technology because it provides the knowledge that is necessary to develop new technologies. Without science, technology would not be possible.

Technology has both positive and negative impacts on society. On the one hand, it has improved our lives in many ways, such as by making it easier to communicate, travel, and access information. On the other hand, it has also created new problems, such as pollution, climate change, and job displacement.

Technology raises a number of ethical issues, including the use of technology to invade people's privacy, the use of technology to create autonomous weapons, and the use of technology to manipulate people's behavior.

The future of technology faces a number of challenges, including the need to develop more sustainable technologies, the need to address the ethical issues raised by technology, and the need to ensure that technology benefits all of society.
