Very few people know that these 11 phrases came from famous speeches

Speeches are a great occasion to include a powerful quote that might resonate with someone in the audience and be passed down through the ages. These 12 notable quotes by politicians, activists, businessmen, and other notable individuals are still referenced today because they remain highly relevant and true. Which one is your favorite?

President John F. Kennedy’s 1961 inaugural address is remembered for its call to public service. Using vivid imagery, he delivered a powerful message.

Its most iconic line, "Ask not what your country can do for you; ask what you can do for your country," remains one of the most quoted phrases in American history.

The famous and ubiquitous line "I have a dream" comes from Martin Luther King Jr.’s iconic 1963 speech during the March on Washington. Though partly improvised, it became the heart of his vision for racial equality and justice.

Inspired by past speeches and by gospel singer Mahalia Jackson’s encouragement, King’s words instilled hope for a future free from discrimination.

The phrase "The only thing we have to fear is fear itself" comes from Franklin D. Roosevelt’s 1933 inaugural address. He spoke these words to calm a nation gripped by fear during the Great Depression.

Roosevelt’s message was clear: fear can be more damaging than the crisis itself. By facing challenges with courage, people could begin to rebuild and move forward.

"The pen is mightier than the sword" expresses the idea that words can have a greater impact than violence. It highlights the power of writing and communication to inspire change and influence people.

Popularized by Edward Bulwer-Lytton in 1839, the idea had been expressed before, but not in the same words.

"Blood, toil, tears, and sweat" comes from Winston Churchill’s first speech as Prime Minister in 1940. He used it to prepare the British people for the hard sacrifices ahead in World War II.

Though similar phrases had existed before, Churchill’s words became iconic. They captured the grit and determination needed to face a long and brutal conflict.

"We are the change we seek," a phrase popularized by Barack Obama, highlights the idea that real change starts with individual action. It encourages people to take responsibility rather than wait for others to lead.

The saying became a central theme of Obama’s 2008 campaign and remains closely associated with him, even though similar iterations of it can be found elsewhere.

While it can sound like a joke, the phrase "speak softly and carry a big stick" was really used in a speech. It refers to using calm diplomacy backed by the ability to act forcefully if necessary.

Theodore Roosevelt popularized the saying as part of his foreign policy. The "big stick" symbolizes power used only when required, while "speaking softly" reflects the value of measured, non-aggressive communication.

"If you can dream it, you can do it" is often linked to Walt Disney, but it was actually written by Disney Imagineer Tom Fitzgerald for the Horizons ride at Epcot.

It encourages people to believe in their dreams and work hard to achieve them. The message is that imagination, paired with determination, can turn vision into reality.

During his famous 2005 Stanford commencement speech, Steve Jobs delivered the phrase "Your time is limited, so don’t waste it living someone else’s life." It is a reminder that life is short and should be lived on your own terms.

Jobs urged people to follow their passions and avoid being trapped by others’ expectations. The message is about staying true to yourself and making the most of the time you have.

An inspiring phrase, "The harder I work, the more luck I seem to have," highlights how effort often leads to success. It suggests that luck favors those who are prepared and persistent.

Though commonly attributed to Thomas Jefferson, its true origin is debated. Regardless of who said it, the message remains clear: hard work increases your chances of good fortune.

This highly inspirational quote closes our list and is attributed to Henry Ford. It reflects his belief in the power of mindset and confidence.

Ford’s message is that your attitude shapes your success. Believing in yourself increases the chances of achieving your goals, while doubt can lead to failure.

DECODING DNA

10 Surprising Facts About Genetics and DNA

Genetics can both fascinate and befuddle us with its complexity, but understanding its mechanisms just might be the key to deciphering the building blocks of our entire existence. From genes that are shared between different species to viruses that insert themselves into our DNA, here are 10 things you—likely—didn’t know about genetics and DNA.

We vastly underestimate the amount of DNA we carry around in our cells. If you were to unravel all the DNA molecules in your body and lay them end to end, they would stretch an astonishing 10 billion miles—enough to reach the moon and back over 40 thousand times! However, despite the vast amount of DNA in our bodies, if we were to gather and weigh all of it together, it would surprisingly amount to only around 8 ounces.

Surprisingly, humans share about 50% of their DNA with bananas! But this shouldn’t be too surprising given the fact that all life on Earth evolved from a single organism, roughly 3.5 billion years ago. Every living creature on our planet has the same type of DNA, undergoing almost identical processes in order to live and reproduce.

Certain species, like salamanders and starfish, possess remarkable regenerative abilities, allowing them to regrow lost limbs. Other species like axolotls or jellyfish can even go further, regenerating anything from parts of their brains to crucial internal organs, or even recovering from being cut in half! Understanding the genetic mechanisms behind this ability holds promise for regenerative medicine and even tissue engineering.

Surprisingly, we inherit slightly more DNA from our mother’s side. While everyone receives 50% of DNA from each parent, a small portion of mitochondrial DNA, which is passed down exclusively from mother to child, contributes to this imbalance. Mitochondrial DNA also allows for tracing the ancient relationships of human populations, and for this reason, it is extensively studied in anthropology and evolutionary biology.

Scientists have already successfully stored digital data within DNA molecules, and many believe the technique has potential as a long-term storage solution. Its vast storage capacity and durability make it very attractive to store digital information, but the technology is still in development.

DNA is sort of a blueprint that determines most of our traits and characteristics, but it is far from having the last say on how particular traits or genes will express themselves. Environmental factors can modify gene expression without changing the underlying DNA sequence, potentially impacting health and development. This is the reason that even identical twins have noticeable differences, like unique fingerprints.

Studies have shown that certain environmental factors experienced by parents, like exposure to stress or traumatic events, can leave chemical marks on DNA that are passed down to offspring. This phenomenon is called transgenerational epigenetic inheritance, and though it seems to contradict some of the tenets of Darwinian ideas, it is now widely accepted as one of the many mechanisms of genetic inheritance in most living organisms.

Rare genetic mutations can give natural immunity to certain diseases. In time, if these genes can be distributed sufficiently within a given population this can even lead to collective immunity. For example, there is a genetic mutation called CCR5-delta 32 that provides natural immunity to the Human Immunodeficiency Virus (HIV) by altering the structure of a specific protein these viruses use to infect cells. Studying these unique phenomena can be promising for developing cures and more effective treatments.

A significant portion of the human genome consists of non-coding DNA, often referred to as "junk" DNA because it does not code for proteins. However, recent research suggests that this non-coding DNA plays important roles in gene regulation and genome stability, challenging the notion of it being just 'junk'.

Horizontal gene transfer is a very weird phenomenon where genetic material is transferred between completely different species, bypassing traditional vertical inheritance from parent to offspring. Although the mechanism behind this process is poorly understood, scientists believe that it played a significant role in the evolution of many organisms. In fact, certain types of viruses force this to happen in order to encode themselves into the DNA of their hosts and reproduce.
