What is the no 1 engineering University of world?

There's no single definitive answer to the question of the world's #1 engineering university. Different ranking organizations (like QS, Times Higher Education, ARWU) use different methodologies and weightings, leading to varying results. Each year, the top spots are often contested among a small group of universities, including (but not limited to):

* Massachusetts Institute of Technology (MIT): Consistently ranks very highly, often at or near the top.

* California Institute of Technology (Caltech): Another US institution known for its strong focus on science and engineering.

* Stanford University: A leading university with a renowned engineering school.

* University of Cambridge: A strong contender from the UK with a long history of engineering excellence.

* University of Oxford: Similar to Cambridge, Oxford also excels in engineering.

* ETH Zurich (Swiss Federal Institute of Technology): A top European university with a strong reputation in engineering and technology.

Ultimately, the "best" university depends on your specific interests within engineering, research opportunities, and personal preferences. Looking at several different rankings can give you a broader perspective.
