 Bismillahir Rahmanir Raheem and Assalamu Alaikum I am Dr. Nagin Hussain I did my PhD in Microbiology and Molecular Genetics. I am going to teach you Bioethics, Biosecurity and Biosafety. Today we will talk about the first topic of Bioethics which is Science, Ethics and Values. So let's discuss what is Science, what is Ethics and what is Values. Science basically comes from a Latin term CO that means to know. So science simply means the knowledge. Now keep in mind that knowledge is not only an observation and then putting it into a theoretical form but it's a combination of observation and then carrying out different experiments so that we can increase more and more observations. Now keep in mind that observation and theoretical form cannot be combined together. Only observations and experiments they can be combined together. Now different people take science in a different way. There is not a single definition of science. Most people take science according to their daily routine. They emphasize on those aspects of science which are more prominent in their lives. Now according to modern science science is an investigation of the universe by a set of methodologies like observation, experiment, conducting out hypothesis and then testing the hypothesis. So there is lots of space in this definition, lots of variety in this definition of science. Now keep in mind that we can't ignore the importance of science in our daily life. Now science progresses step-wise. It is not a name of a single activity or a single practice. So observations, experiments, they come out to know about the scientific knowledge, about the scientific understanding of the literature. This is all done by the scientific methods. So science is not a value-free. We need a lot of fun to improve the scientific research. Now what is ethics? Ethics, what is it? It is mainly associated with science. Now scientists are trying to solve the ethical issues. For example it can be an animal concern, it can be an environment concern, it can be participation of human subjects, ethics related to cloning, ethics related to stem cell program. So it can be any ethical issue that can be raised by the scientific methods. Now, today's scientists are trying to solve these problems in the 21st century so that scientific research can be more useful in the practical life. Now, what is value? Value is something that worth to us. So proper resource allocation is very much important because it reflects what society at the time seemed to be valuable. So we can't improve the science, ethics and values. They are interconnected. When we talk about the science, we always talk about the ethical issues. And when we talk about the ethical issues, we talk about the value of the society.
