Symmetry, as it is understood, seems not to answer the biggest questions in physics. In some cases, symmetries show the underlying laws of nature that do not show up in reality.
For example, when energy congeals into matter (E = mc2), the result is an equal amount of matter and antimatter - a symmetry. Yet if the energy of the Big Bang created both matter and antimatter equally, they should have destroyed each other, leaving nothing behind.

Albert Einstein did not think about symmetry when he wrote his first relativity papers in 1905. He was considering several seemingly unrelated puzzles and connecting the dots.
Einstein's special theory of relativity applies only to steady, unchanging motion through space-time, not accelerating motion like an object falling toward Earth.
From the 1950s, invariances took on a life of their own. New symmetries, known as "gauge" invariances, became productive by requiring the existence of everything from W and Z bosons to gluons.
Gauge symmetry dictates what other ingredients you have to introduce. Gauge symmetries d...
The idea of symmetry proved very powerful. Giving it up would mean giving up on naturalness - the idea that the universe has to be exactly the way it is for a reason.
But inside black holes, the speed of light (which grounded Einstein's work) will not play a vital role in the future....
The most fundamental aspects of nature stay the same.
For example, Einstein's papers on relativity show that the relationship between energy and mass is invariant, even though energy and mass can take on many different forms.
Even though matter produces ene...
The relationship that mattered most to Einstein's ideas was symmetry. Scientists describe symmetry as changes that don't really change anything. More complicated symmetries have led to the discoveries from neutrinos to quarks.
Symmetry is at the root of our descrip...
After Einstein, the pull of symmetry became more powerful.
Many insights of Albert Einstein are now part of popular imagination: black holes, time warps, and wormholes show up in movies and books.
Less famous, but probably the most revolutionary part of Einstein's phenomena, is a simple idea that shows how pieces fit together and illuminate the ro...
Unified space-time starts to make sense if we think that the speed of light is a relationship between the distance traveled over time.
Because the speed of light can't change, your laser beam won't go any faster. The measurement of distance and time must be changed instead, depending on th...
We often think of things as the heart of reality. But most often the relationship is more important, not the stuff.
We may think "stuff" like space and time are unchangeable aspects of nature. In reality, the relationship between space and time stays the same.
Duality is a closely related idea to symmetry. Wave-particle duality has been around since the beginning of quantum mechanics. But newfound dualities have shown interesting relationships. For example, a three-dimensional world without gravity can be mathematically equivalent to a fou...

Best app ever! You heard it right. This app has helped me get back on my quest to get things done while equipping myself with knowledge everyday.
Great interesting short snippets of informative articles. Highly recommended to anyone who loves information and lacks patience.
Don’t look further if you love learning new things. A refreshing concept that provides quick ideas for busy thought leaders.
This app is LOADED with RELEVANT, HELPFUL, AND EDUCATIONAL material. It is creatively intellectual, yet minimal enough to not overstimulate and create a learning block. I am exceptionally impressed with this app!
Great for quick bits of information and interesting ideas around whatever topics you are interested in. Visually, it looks great as well.
I have only been using it for a few days now, but I have found answers to questions I had never consciously formulated, or to problems I face everyday at work or at home. I wish I had found this earlier, highly recommended!
Brilliant. It feels fresh and encouraging. So many interesting pieces of information that are just enough to absorb and apply. So happy I found this.
Even five minutes a day will improve your thinking. I've come across new ideas and learnt to improve existing ways to become more motivated, confident and happier.
