A Mathematician's Love Letter

De-Morgan's Law,

Binomial Avenue,

United States of Matrices.

My Dear Love,

Yesterday, I was passing by your rectangular house in trigonometric lane. There I saw your cute circular face,conical nose and spherical eyes,standing in your triangular garden.

Before seeing you my heart was a null set, but when a vector of magnitude (likeness) from your eyes at a deviation of theta radians made a tangent to my heart, it differentiated.

My love for you is a quadratic equation with real roots, which only you can solve by making good binary relation with me.

The cosine of my love for you extends to infinity. I promise that I should not resolve you into partial functions but if I do so, you can integrate me by applying the limits from zero to infinity. You are as essential to me as an element to a set. The geometry of my life revolves around your acute personality. My love, if you do not meet me at parabola restaurant on date 10 at sunset, when the sun is making an angle of 160 degrees, my heart would be like a solved polynomial of degree 10. With love from your higher order derivatives of maxima and minima, of an unknown function.

Yours ever

loving,

Pythagoras

How Thermos keeps coffee Hot or Lemonade Cool...

According to Prevost's Theory of Exchange, the colder of two bodies always absorbs heat waves until both bodies are the same temperature. By this theory, it would be natural for scalding coffee or ice-cold lemonade in a thermos to lose heat or gain it respectively. But a thermos is designed to cut down the exchange of heat between the inside and the outside of the bottle by hampering the three ways in which heat can travel: Conduction, Convection and Radiation.

How to control our mind?

• Mind can be controlled by constant effort to fix it on God.
• Sit alone and watch the mind and its moments.
• Be indifferent and unattached. Remain a witness. Do not identify yourself with the thoughts.
• Do not think of the past. Do not plan for future. Live in the present.
• Read spiritual books. Do meditation regularly. Participate in satsang.
• Do help a person in need or suffering.
• Repetition of a mantra destroys impurities of the mind.
• Make the mind inward. In this Kali Yuga, the easiest way for controlling the mind is singing the Lord's name.
• Food influences the mind. Take fruits, vegetables and nuts frequently.
• Practise moderation in diet. Selfless service with a feeling of unity with everyone is highly effective in purifying the mind. Do no struggle with the mind.
• Be regular in your sadhana.
