While Einstein is most renowned for his theory of relativity, it was his explanation of the photoelectric effect that earned him the Nobel Prize in Physics in 1921. The photoelectric effect describes how light can eject electrons from a metal surface, a phenomenon that classical physics couldn’t explain.

Einstein introduced a groundbreaking concept. He said that light behaves as both a wave and a particle. This fundamentally reshaped our understanding of light and laid the groundwork for quantum mechanics.

Einstein’s theory of relativity introduced the concept that the speed of light is the ultimate speed limit in the universe. The theory suggests that when an object approaches the speed of light, its mass and energy increase indefinitely. It establishes a cosmic speed limit that is unsurpassable.

This groundbreaking idea has had a lasting impact on physics, fundamentally altering how we perceive space, time, and motion.

Einstein’s fascination with physics began at a very young age. At just five years old, he was captivated by the invisible forces that moved the needle of his compass. By twelve, he had taught himself geometry from a textbook he affectionately called his “holy geometry book.”

This early curiosity and self-driven learning set the stage for his lifelong quest to understand the mysteries of the universe.

Einstein was a scientific genius and a passionate advocate for peace and social justice. He was a vocal opponent of militarism and nationalism, famously leaving Germany at 16 to avoid mandatory military service. He even called nationalism “the measles of the human race.”

In 1952, he was offered the presidency of Israel, a testament to his global influence and respect. However, he declined because of his inexperience in dealing with people. He was also physically unable to take on the role.

Albert Einstein’s life was a blend of extraordinary intellect, curiosity, and a deep sense of justice. His contributions to science extend far beyond his famous equations, influencing countless areas of research and societal thought.

These five facts provide a glimpse into the man behind the legend, illuminating the diverse aspects of his legacy that still captivate and fascinate us today.

If you have been using your iPhone for quite some time, you might notice that it might not be as loud as it once was. This can be an issue when you are using your phone for regular tasks, such as listening to music or making phone calls, and it turns out that it can be resolved without changing the whole speaker. Have you tried cleaning it?

An iPhone Can Get Dirty

A video, recently posted on Facebook, shows how dirty an iPhone can become by demonstrating how the speakers become blocked with all types of filth. The video shows a specialist painstakingly removing debris with a sharp tool. One Facebook user suggested blu tack instead if you are trying to do this yourself. The user also wrote that the most effective way to use blu tack is to carefully press it into the perforations of the speaker. Remove the blu tack and repeat the whole process until the speakers are clean.

Sharp Tools Can Do Damage

This warning is for people who are not that experienced in doing such activities. Using sharp tools can damage the speakers of your iPhone. In the meantime, another Facebook user wondered how a phone could get so filthy. Truth is, working with sawdust, drywall dust, cement dust, etc. can contribute to this, filling the speakers with all kinds of debris. Not to mention that your iPhone is probably in your pocket most of the time, which is an easy way for fabric from your clothes to get stuck in the speakers or microphone of your device. Just be careful while cleaning it because it may seem easy at first, but you might end up doing damage to your speakers.

If you want to clean your iPhone in any way, Apple suggests that you do so only after turning it off and disconnecting it from any cables. This is the safest approach to cleaning this device.
