It took me 4 years to play Rachmaninoff's Prelude in C-sharp minor
Rachmaninoff's Prelude Op. 3 No. 2 is one of the most dramatic and powerful works ever written for piano. When I first heard it many years ago somewhere on UA-cam, I was impressed by its emotional depth and unusual melody. I thought, what if I spent some time learning to play it myself?
Back then I was a self-taught amateur pianist with very limited skills and knowledge of music theory. I managed to memorise all the notes of the Prelude in about one year. Yet, I was far away from playing it adequately. I realised that this was a piece for professional pianists - I simply did not have the necessary technical skills and precision to play complex passages and constantly make rapid shifts. Without making much progress in mastering the Prelude, I lost a bit of interest and didn’t practice it much.
Then, a few years later, I came back to the Prelude and realised that I could understand it more deeply and play it better. I decided to push harder so that I could record this piece one day and share it without embarrassment. After countless weeks of practising, I can now play the famous Rachmaninoff's Prelude. This is a great achievement for me and another proof that anything is possible with dedication and time.
I was not alone in this journey. I would not have succeeded without the guidance of my piano teacher, Alexander Velikovskiy www.youtube.com/@AlexanderVelikovskiy
Thank you, Alexander!

I have been discussing the problem of publishing pressure in academia with many researchers and professors. I found that some good professors are aware of this problem and try to avoid toxic publishing practices. In this video, I share three stories about publishing pressure that show positive changes in academia. 00:00 Publishing pressure 00:34 Some professors know about it 01:31 Story #1: Den...

This is my second talk at the PowerTech 2023 Belgrade conference (powertech2023.com/). Using a realistic meshed distribution system from the UK, I demonstrate that network reconfiguration can increase the limits of aggregated flexibility and improve the economic efficiency of flexibility markets. The slides are based on our recent work "Impacts of Distribution Network Reconfiguration on Aggrega...

The value of papers in academia is a very sensitive topic that I have been thinking about for quite some time. Yes, writing a paper is a great way to study the topic and advance your knowledge. Yes, papers are generally considered the best tool for disseminating scientific results. Papers are the structure and the soul of any research. But the value of a single paper can be very low sometimes. ...
