The highest form of pure thought is in mathematics. Plato Do not worry about your difficulties in mathematics. I can assure you that mine are still greater. Albert Einstein Pure mathematics is, in its way, the poetry of logical ideas. Albert Einstein The essence of mathematics is not to make simple things complicated, but to make complicated things simple. Stan Gudder Mathematics, rightly viewed, posses not only truth, but supreme beauty; a beauty cold and austere, like that of sculpture. Bertrand Russell Film is one of the three universal languages, the other two: mathematics and music. In mathematics the art of asking questions is more valuable than solving problems.

“The most important thing in communication is to hear what isn't being said.” “Trying to predict the future is like trying to drive down a country road at night with no lights while looking out the back window.” “The only thing we know about the future is that it will be different.” “We now accept the fact that learning is a lifelong process of keeping abreast of change. And the most pressing task is to teach people how to learn.” “Meetings are a symptom of bad organization. The fewer meetings the better.” “Whenever you see a successful business, someone once made a courageous decision” “Efficiency is doing things right; effectiveness is doing the right things.” “Time is the scarcest resource and unless it is managed nothing else can be managed.” “Doing the right thing is more important than doing the thing right.” “One cannot buy, rent or hire more time. The supply of time is totally inelastic. No matter how high the demand, the supply will not go up. There is no price for it. Tim...

“To learn to read is to light a fire; every syllable that is spelled out is a spark.” Victor Hugo “A capacity and taste for reading gives access to whatever has already been discovered by others.” Abraham Lincoln “When you sell a man a book you don't sell him just 12 ounces of paper and ink and glue - you sell him a whole new life.” Christopher Morley “No matter how busy you may think you are, you must find time for reading, or surrender yourself to self-chosen ignorance.” Confucius “Reading without reflecting is like eating without digesting.” Edmund Burke “Some books are to be tasted, others to be swallowed, and some few are to be chewed and digested.” Francis Bacon “Every reader finds himself. The writer's work is merely a kind of optical instrument that makes it possible for the reader to discern what, without this book, he would perhaps never have seen in himself.” Marcel Proust “Anyone who says they have only one life to live must not know how to read a book”.

The best way to cheer yourself up is to try to cheer somebody else up. Mark Twain If you want to be happy, be. Leo Tolstoy Happiness is not an ideal of reason, but of imagination. Immanuel Kant If there were in the world today any large number of people who desired their own happiness more than they desired the unhappiness of others, we could have a paradise in a few years. Bertrand Russell My crown is called content, a crown that seldom kings enjoy. William Shakespeare You cannot always have happiness, but you can always give happiness. Author Unknown Happiness always looks small while you hold it in your hands, but let it go, and you learn at once how big and precious it is. Maxim Gorky Some pursue happiness, others create it. Author Unknown The best way for a person to have happy thoughts is to count his blessings and not his cash. Author Unknown Being happy is something you have to learn. I often surprise myself by saying "Wow, this is it. I guess I'm happy. I got ...

"The most successful men in the end are those whose success is the result of steady accretion. . . It is the man who carefully advances step by step, with his mind becoming wider and wider and progressively better able to grasp any theme or situation , persevering in what he knows to be practical, and concentrating his thought upon it, who is bound to succeed in the greatest degree." Alexander Graham Bell "Try not to become a man of success, but rather to become a man of value. He is considered successful in our day who gets more out of life than he puts in. But a man of value will give more than he receives." Albert Einstein "The first requisite of success is the ability to apply your physical and mental energies to one problem without growing weary." Thomas Edison "I've failed over and over and over again in my life and that is why I succeed." Michael Jordan Many of life's failures are people who did not realize how close they were to s...

Let me tell you the secret that has led me to my goal: my strength lies solely in my tenacity. Whether our efforts are, or not, favoured by life, let us be able to say, when we come near the great goal: I have done what I could. Science knows no country, because knowledge belongs to humanity, and is the torch which illuminates the world. Science is the highest personification of the nation because that nation will remain the first which carries the furthest the works of thought and intelligence. There are no such things as applied sciences, only applications of science. I am utterly convinced that Science and Peace will triumph over Ignorance and War, that nations will eventually unite not to destroy but to edify, and that the future will belong to those who have done the most for the sake of suffering humanity. In the fields of observation chance favours only the prepared mind. (Louis Pasteur)

Laughter is the sun that drives winter from the human face. Music expresses that which cannot be said and on which it is impossible to be silent. People do not lack strength; they lack will. Short as life is, we make it still shorter by the careless waste of time. To be perfectly happy it does not suffice to possess happiness, it is necessary to have deserved it. If a writer wrote merely for his time, I would have to break my pen and throw it away. (Victor Hugo)

Since I have launched this weblog in 2005, or arguably in 2003, I always had a temptation to gather a collection of profound and thoughtful quotes here. However, for the sake of consistency in the weblog’s content, I always kepts my posts’ theme related to my research and teaching interests. Nevertheless, now I can not see any reason for not mentioning some inspirational quotes once in a while. Therefore, today I make a new category here and I call it “Inspirational Quotes”. I begin this new chapter by some insightful quotes from Helen Keller, the American author and educator who was blind and deaf (1880-1968): "When one door of happiness closes, another opens; but often we look so long at the closed door that we do not see the one which has been opened for us.” “The best and most beautiful things in the world cannot be seen or even touched. They must be felt with the heart.” “I am only one, but still I am one. I cannot do everything, but still I can do something; and because I ca...
