Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: Three physicists received the 2025 Nobel Prize in Physics for demonstrating macroscopic quantum tunneling, which enables quantum computing development and improves medical imaging technology.
📈 One key stat: The researchers confirmed quantum tunneling by cooling their experimental apparatus to within a fraction of a degree of absolute zero, revealing tunneling effects that persist even at extremely low temperatures.
💬 One key quote: “Quantum computing remains one of the most exciting opportunities which is promised for the near future, and is the source of significant investment worldwide.”
1️⃣ The big picture: The 2025 Nobel Prize in Physics honors John Clarke, Michel Devoret, and John Martinis for groundbreaking experiments demonstrating quantum tunneling in macroscopic systems. Their work about 40 years ago proved that quantum particles can pass through barriers in ways that defy classical physics, even in larger, visible systems. This discovery coincides with the 100th anniversary of quantum mechanics and has transformed our understanding of quantum effects. The laureates’ experiments with superconducting circuits ultimately laid crucial groundwork for modern quantum computing technology and various medical applications.
2️⃣ Why is this good news: The experimental confirmation of macroscopic quantum tunneling opened entirely new possibilities for technological advancement. This discovery directly supported the development of quantum computers, which promise to solve complex problems beyond the capabilities of traditional supercomputers. The principles are already applied in superconducting quantum interference devices (SQUIDs) that detect minute magnetic field variations, helping locate underground minerals and creating high-resolution medical images of tumors. These quantum effects also improve brain imaging for epilepsy management and enhance the function of MRI machines used in hospitals worldwide.
3️⃣ What’s next: Further refinement of quantum computing technology continues, potentially revolutionizing encryption and computational capabilities. Researchers will keep exploring applications in medicine, particularly for improved diagnostic imaging. The Nobel committee’s recognition may accelerate funding and development of consumer-oriented quantum technologies.
