Going back to the start, how did you come to studying Theoretical Physics?
As with most people my path was determined by a series of choices involving random factors. I liked mathematics and physics at school, and did well in the olympiads, but I liked also literature, history, etc. At the age of fourteen I choose a technical-type high school oriented at nuclear disciplines, as popular then as they are despised by many these days, probably because it was one of the most difficult and challenging ones.
The way from there to the Technical University was straightforward. Since I have the need to understand things from the first principles, I drifted gradually towards theoretical physics and it was only natural that in the middle of my studies, corresponding roughly to the bachelor degree nowadays, I ended up at the Theoretical Physics Department of the Charles University, where I subsequently graduated.

“In a letter written in 1871, the Symbolist poet Arthur Rimbaud uttered a phrase that announces the modern age: “‘Je’ est un autre” (“‘I’ is someone else”). Some 69 years later I entered the world as an identical twin, and Rimbaud’s claim has an uncanny truth for me, since I grew up being one of a pair. Even though our friends and family could easily tell us apart, most people could not, and I began life with a blurrier, more fluid sense of my contours than most other folks.”

Directed by Carl Loeffler, The Networked Virtual Art Museum was a pioneering project that investigated telecommunications and virtual reality, and provided a basis for multiple users located in distant geographical locations to be conjoined in the same virtual, immersion environment. The project employed telecommunication hardware, as well as the hardware associated with virtual reality: data eyephones and multi-directional navigation devices. The immersion environment was an art museum with galleries offering various exhibitions.

I learn useful life lessons from each patient I meet. Some are positive messages, reminding me of the importance of maintaining balance between family, work, and leisure activities, but more frequently I witness examples of the remarkable resilience of the human spirit when facing the reality and risks of a major surgical procedure and a diagnosis of cancer. Rarely, patients and their family members utter remorseful or simply sad remarks when they are faced with a grim prognosis and the emotions associated with an onrushing date with mortality. These comments invariably involve an inventory of regrets in life, including, “I should have spent more time with my kids,” “I wish I had told my father (or mother, brother, sister, child, or some other person) that I loved them before they died,” and “I have spent my entire life working, I never took time for anything else.” I wince when I hear these openly expressed remonstrations, I recognize that I am hearing painful and heartfelt truths. Not a week goes by that I am not reminded that I do not one day want to look back at my life with a long list of regrets, should have dones, and what ifs.
I was blessed to meet a great teacher in the guise of a patient early in my academic career. He came to my clinic in my first year after completing a Fellowship in Surgical Oncology, my first year as an Assistant Professor of Surgery. My patient was a 69 year-old Baptist Minister from a small town in Mississippi. He was referred to me by his medical oncologist who called me and said, “I don’t think there is anything you can do for him, but he needs to hear that from you because he doesn’t believe me.” This tall, imposing man had colon cancer that had metastasized (spread) to his liver. The malignant tumor in his colon was removed the year before I met him, and he had received chemotherapy to treat several large tumors found in his liver. The chemotherapy had not worked and the tumors grew. At the point I met him, the medical oncologist told him he would live no more than 6 months, and because he was an avid fisherman when not preaching or helping others in his community , the doctor suggested that he go out and enjoy his remaining time by getting in as much fishing as possible. I learned two invaluable lessons from this patient and his family. First, never deny or dismiss hope from a patient or their family, even when from a medical perspective the situation seems hopeless and the patient is incurable. Second, quoting the minister directly, “Some doctors think of themselves as gods with a small ‘g’, but not one of you is God”.
When I first walked into the examining room, this man was slouched on the examining table in the perfunctory blue and white, open-backed, always unflattering hospital gown. He made eye contact with me briefly, then looked down to the floor. In that momentary meeting of our eyes, I saw no sparkle, no life, no hope in his eyes. He responded to my initial questions with a monotonic and quiet voice. Several times I had to ask him to repeat an answer because his response was so muted. Mid-way through our first visit, the patient’s wife told me he had been very depressed by his diagnosis of untreatable metastatic colon cancer. She reported, despite his occasional side-long warning glances requesting her silence, that while he was eating well, he was spending most of his time sitting in a chair or laying in bed, and that the active, gregarious man with the quick wit and booming voice she had married was gone.

What are the prime factors, or multipliers, for the number 15? Most grade school students know the answer — 3 and 5 — by memory. A larger number, such as 91, may take some pen and paper. An even larger number, say with 232 digits, can (and has) taken scientists two years to factor, using hundreds of classical computers operating in parallel.
Audi RSQ – a fantastic car. Certainly a design icon, but first of all, a movie star. The Audi RSQ was the first car we developed for a motion picture – with great success. This sporty coupé for the 2004 Hollywood science-fiction “I, Robot” was a visionary concept of what a car might look like in 2035. Four designers, ten model engineers, ten weeks, all creative liberties – that’s what it took to create this Audi of the future.
What was really unique and visionary about the Audi RSQ: It was the first Audi demonstrating piloted driving capabilities. Here is one of my favorite moments in the movie – a moment that tells you a lot about piloted driving:

I fully support this only when the net and infrastructure is secured from hackers.
Artificial intelligence should be used to provide children with one-to-one tutoring to improve their learning and monitor their well-being, academics have argued.
One-to-one tutoring has long been thought the most-effective approach to teaching but would be too expensive to provide for all students.
