At first sight the two seems are unrelated. But they are because when you run, your body start to get warm because you are using energy. When you
drive a car, it also gets warm because you are burning fuel. When you heat up matter, the velocity of molecules increases too thereby increasing pressure, Boyle’s- Charles’ law.
More recently it was discovered that the speed of light can be controlled by temperature too. Prof. Lene Hau from MIT and her team showed in an experiment that at extremely low
temperature close to zero kelvin, a beam of light passing through, is slows down to 0 m/s.
 
 
Can we protect technology to be only for good use?
28/07/2025
I think that often techonologists overlook or underestimate the potential of danger their innovation can bring to innocent people. Probably no harm is intend,
but problems start when these powerful tools get in the wrong hands.
I can remember when I was young, we still went to the post office to collect and send letters. When email and other digital messaging services
became more accessible, it seemed like we are losing something, we are becoming lazy, and reliant on this new way of doing things. This is what
technology is, and it dates back many centuries, and will probably continue to change people’s lives in the future.
Today’s technology is arguably bringing the biggest transformation of the century. I am speaking about the man-made intelligence, yes AI.
I know it’s the last thing you probably want to read about, so am I honestly. But I personally think that these tools have gone too far in some cases and need serious
consideration before releasing to the public and I really wish that by the time that measures are being taken it is not too late.
 
 
Vehicles of the future talk
21/06/2025 Edited:10.08.2025
"From fuel to hybrid, electric, hydrogen and solar - the future of transportation is diverse fast-moving, and full of opportunity for students. But preparing students for this future goes beyond understanding engines. it requires strong foundation in the supporting trades that make mobility"
This is an excellent topic and very relevant to the audience. My talk was customised to align the topic with the Autonomous vehicles. And how they work as they are a key player in this topic particulary when it comes to efficiency
improvement. I also wanted to express my disappoint with the automotive industry. Knowing that electric cars were actually popular in the 1900s. For whatever reason they lost popularity, and the Internal Combustion Engine cars overtook them. had we sticked with EVs we would have refined them and made them more reliable today. But it's not too late,
each one of us needs to play a part in diversifying energy sources, little as it can be, it counts.
I am also very greatful for the organisers for writing me this warm message after the event:

24/06/2025
I am delighted to announce that my book is nominated for creative non-fiction award. Just being noninated
alone represents a milestone for me. and I want to thank many of my supporters and nominators for seeing
potential in my work and taking their time to nominate it.
This work has been tranformative and theraputic. there are also downsides and those are that I have become
mostly unavailable to get together. I really hope that my friends and family realises what it was all for and
the payoff of my hardwork and their support is starting to show. sala.org.za
 
 
Why do faults still occur even with preventative maintenance in effect?
20/04/2025
The thing is that managing maintenance of small to medium machines is really easy, also the cost is relatively low. When it comes to large
integrated systems that involves more professionals such as meterials specialist, Electrical/ Mechanical/ Mechatronics engieers, computer scienctist etc.
it becomes more difficult, to isolate problems. since these systems are developed over time by several groups of people.
Information gets lost overtime, also with upgrades it can be tricky to handle old and new system documentation. It would be easy to just discards
old documentation, but in reality it's not so easy because we often refer to multiple documentation during repairs,
upgrade and troubleshooting. The knowledge of interconnectivity of these system sort of gets more complex and spread among the employees
to the point that simple repairs takes longer than necessary as a result of the time taken to figure out how systems and components are configured.
In some cases an overhaul of such systems is necessary, however it does not happen because of the economics.
luckily modern systems are becoming multi-compatible and more standardised as compared to the previous years. thanks to platforms and protocols
such as TCP/IP, OPC UA, Node-red, it is also much easier to find documentation online. However so much effort still needs to be taken to document
changes and improvements of systems. this is going to require up skilling of systems integrators and engineers or employing technical writers to
clearly document their work in a standardised manner.
 
 
Why is it important for Organisation to streamline their processes by digital means
26/03/2025
Implementing digital processes to streamline operations is crucial for the success of any organisation. It allows for efficient management of tasks, enhances
productivity, and provides valuable insights for decision-making. Digitalisation has revolutionised the way businesses operate, enabling seamless communication,
data management, and improved workflow.
Digitalisation has been a key strategy for companies worldwide for many years. Initially, it was primarily utilised by administrative and financial departments to
store, manage, and distribute documents electronically. The shift from paper-based systems to digital platforms brought about significant advantages, such as increased
accessibility, faster document sharing, and improved data security.
The benefits of streamlining business processes through digital means are manifold. It enables organisations to accurately measure performance, identify inefficiencies,
and reduce errors. This, in turn, leads to cost savings, effective implementation of LEAN management principles, and improved overall efficiency. The integration of
technologies like Artificial Intelligence further enhances predictive capabilities, allowing for proactive identification and resolution of operational inefficiencies.
While the initial cost of implementing digital processes can vary, organisations often possess the necessary resources to undergo this transformation. However, these
resources may be underutilised due to factors such as lack of knowledge or expertise among staff members. Overcoming these challenges presents an opportunity for
organisations to harness the full potential of digital tools and systems to drive innovation and growth.
Conclusion
In conclusion, the adoption of digital processes is essential for organisations seeking to streamline their operations, enhance performance, and stay competitive in today's
dynamic business landscape. By leveraging digital technologies effectively, businesses can unlock new opportunities for growth, efficiency, and success.

Reconciling classical and quantum physics
08/12/2020
When observing fractal equations or animations like the Mandelbrot set, we can notice similarities in the appearance and characteristics of small and large things such
as sub-atomic particles, atoms, molecules, and nebulae. This resemblance might be an indication of a fractal nature. Sub-atomic particles exhibit peculiarities like quantum
entanglement, which is exclusive to them due to their distinct experience of space-time compared to larger objects. Despite the distance between them, entangled particles influence
each other because they follow different rules in space-time.
