...But reading that she is a lecturer at the Royal Dick School....???

For dog food, here's a great site for analyzing the quality of feed.

Dog Food Analysis - Reviews of kibble

Thanks for sharing- I look forward to the course

As far as the knowledge being theoretical or practical... it's always good to take all such information with a grain of salt and decide for yourself what makes sense and works in your particular situation. It seems like there are always 50 different STRONG opinions on any subject when it comes to horses!

I am a Turk from Istanbul, but this course has nothing to do particularly with Turkey. Its a course of Coursera, which -quoting from Wikipedia- "is an education technology company founded by computer science professors Andrew Ng and Daphne Koller from Stanford University, located in Mountain View, California." More info can be found on their site, on Wikipedia or via Web search.

Science is the sole valid tool to understand the material world.

But its important to be careful of the following:

1- Science can not find absolute solutions. Science itself evolves and finds better solutions.
2- At a particular time several scientists can claim several solutions to problems and for sure some of them might not be valid. This is something to be solved by further research.
3- There exist pseudo-science and charlatans not to be confused with science and scientists.
4- Advices of all academicians might not be well compatible scientific methods and you may call them "bad scientists" if you like.

Some knowledge of history of science would be useful for all and every of us.

But repeating what I initially wrote: Science is the sole valid tool to understand the material world.

No need to try to -again and again- verify the observation of Charles Darwin: "ignorance more frequently begets confidence than does knowledge."
