Sixteen-year-old and not-so-openly gay Simon Spier prefers to save his drama for the school musical. But when an email falls into the wrong hands, his secret is at risk of being thrust into the spotlight. Now Simon is actually being blackmailed: if he doesn’t play wingman for class clown Martin, his sexual identity will become everyone’s business. Worse, the privacy of Blue, th...(展开全部)

The initial problem wasn't so much 'Who is Simon Warwick?' as 'Where is Simon Warwick?' When old Lord Charlton knew he was dying, he suddenly decided to alter his will and leave his vast fortune to a long-lost nephew. His family solicitor was instructed to trace the young man. Orphaned as a baby during the war, the boy had been adopted by an American officer and his English wif...(展开全部)

Simon Bolivar was a revolutionary who freed six countries, an intellectual who argued the principles of national liberation, and a general who fought a cruel colonial war. His life, passions, battles and great victories became embedded in Spanish American culture almost as soon as they happened. This is the first major English-language biography of 'The Liberator' in half a cen...(展开全部)

简介：很逆天的小说，整活向，含大量私设和ooc

Pierre-Simon Laplace (1749-1827) is remembered amoung probabilitists today particularly for his "Theorie analytique des probabilites", published in 1812. The "Essai philosophique dur les probabilites" is his introduction for the second edition of this work. Here Laplace provided a popular exposition on his "Theorie". The "Essai", based on a lecture on probability given by Lapla...(展开全部)

罗伯特·福格尔（Robert W. Fogel），美国著名经济学家、芝加哥经济学派代表人物之一、芝加哥大学教授、芝加哥大学商学院“人口经济学中心”（Center for Population Economics）主任；他用经济史的新理论及数理工具重新诠释了过去的经济发展过程，以他在计量经济史方面出色的工作荣获了1993年诺贝尔经济学奖。
