Answer the questions at the end based on the text.

Leonhard Euler ( ; ; ; 15 April 170718 September 1783) was a Swiss mathematician, physicist, astronomer, logician and engineer who made important and influential discoveries in many branches of mathematics like infinitesimal calculus and graph theory while also making pioneering contributions to several branches such as topology and analytic number theory. He also introduced much of the modern mathematical terminology and notation, particularly for mathematical analysis, such as the notion of a mathematical function. He is also known for his work in mechanics, fluid dynamics, optics, astronomy, and music theory.

Euler was one of the most eminent mathematicians of the 18th century, and is held to be one of the greatest in history. He is also widely considered to be the most prolific mathematician of all time. His collected works fill 60 to 80 quarto volumes, more than anybody in the field. He spent most of his adult life in Saint Petersburg, Russia, and in Berlin, then the capital of Prussia.

A statement attributed to Pierre-Simon Laplace expresses Euler's influence on mathematics: "Read Euler, read Euler, he is the master of us all."

Leonhard Euler was born on 15 April 1707, in Basel, Switzerland to Paul III Euler, a pastor of the Reformed Church, and Marguerite Brucker, a pastor's daughter. He had two younger sisters: Anna Maria and Maria Magdalena, and a younger brother Johann Heinrich. Soon after the birth of Leonhard, the Eulers moved from Basel to the town of Riehen, where Euler spent most of his childhood. Paul Euler was a friend of the Bernoulli family; Johann Bernoulli was then regarded as Europe's foremost mathematician, and would eventually be the most important influence on young Leonhard.

Q: True Manliness

"Please, mother, do sit down and let me try my hand,"said Fred Liscom, a bright active boy, twelve years old. Mrs. Liscom, looking pale and worn, was moving languidly about, trying to clear away the breakfast she had scarcely tasted.

She smiled and said, "You, Fred, you wash dishes?"

"Yes, indeed, mother," answered Fred. "I should be a poor scholar if I couldn't, when I've seen you do it so many times. Just try me."

A look of relief came over his mother's face as she seated herself in her low rocking chair. Fred washed the dishes and put them in the closet. He swept the kitchen, brought up the potatoes from the cellar for the dinner and washed them, and then set out for school.

Fred's father was away from home and as there was some cold meat in the pantry , Mrs. Liscom found it an easy task to prepare dinner. Fred hurried home from school, set the table, and again washed the dishes.

He kept on in this way for two or three days, until his mother was able to resume her usual work. He felt amply rewarded when the doctor, who happened in one day, said, "Well, madam, it's my opinion that you would have been very sick if you had not kept quiet."

The doctor did not know how the "quiet" had been secured, nor how the boy's heart bounded at his words. Fred had given up a great deal of what boys hold dear, for the purpose of helping his mother, coasting and skating being just at this time in perfection.

Besides this, his temper and his patience had been severely tried. He had been in the habit of going early to school and staying to play after it was dismissed.

The boys missed him and their curiosity was excited when he would give no other reason for not coming to school earlier, or staying after school, than that he was "Wanted at home."

"I'll tell you," said Tom Barton, "I'll find him out, boys-see if I don't!"

So, one morning on his way to school, he called on Fred. As he went around to the side door, he walked lightly and somewhat nearer the kitchen window than was ly needful. Looking in, he saw Fred standing at the table with a dishcloth in his hand.

Of course he reported this at school, and various were the greetings poor Fred received at recess ."Well, you're a brave one to stay at home washing dishes!""Girl boy!" "Pretty Bessie!""Lost your apron, haven't you, Polly!"

Fred was not wanting either in spirit or in courage, and he was strongly tempted to resent these insults and to fight some of his tormentors . But his consciousness of right and his love for his mother helped him.

While he was struggling for self-mastery, his teacher appeared at the door of the schoolhouse. Fred caught his eye, and it seemed to look, if it did not say, "Don't give up! Be really brave!" He knew the teacher had heard the insulting taunts of his thoughtless schoolmates.

The boys received notice during the day that Fred must not be taunted in any manner. They knew that the teacher meant what he said; and so the brave little boy had no further trouble.
