简介：不用说，接受这份殊荣，我十分荣幸。除了为多年来关心物理教育的各种问题而感到乐趣之外，我特别高兴在10年前就致力于AAPT的各种活动。它让我了解在座的许多人的工作，使我谦虚，很清楚，你们中间许多人都有可能象我今天这样站在领奖台上。

简介：我们为f(T)严肃理论在宇宙论的限制的精确上探索SandageLoeb(SL)测试的影响。因为它在远类星体的系列在Lyman-森林里测量redshift飘移，SL测试是对当前的宇宙论的观察的重要补充，盖住2z的redshift沙漠5。避免数据矛盾，当模仿30的基准的模型嘲笑SL测试数据，我们基于当前的联合观察数据使用最好合适的模型。我们确定为f(T)严肃理论的参数评价上的这些SL测试数据的影响。二个典型f(T)模型被考虑，幂定律模型f(T)PL和指数形式的模型f(T)终止。结果证明SL测试罐头有效地打破存在在在另外的宇宙论的观察的今日的事密度m和小瘤常数H0之间的强壮的退化。为考虑f(T)模型，SL测试的30年的观察能极其改进m和H0的限制精确，但是不能有效地改进模型参数的限制精确。

简介：在这份报纸，我们学习稳定性局部地旋转地对称(LRS)Bianchi我在通过阶段空间分析的f(T)重力的宇宙模型。我们假设f(T)严肃能被当作象完美的液体一样表现的有效黑暗精力，并且建议在无压力的物质以及黑暗精力之间有相互作用。我们构造方程的相应自治系统检查模型的稳定性因为非幽灵，真空和幽灵分阶段执行。批评的点作为与相比在幽灵阶段仍然保持更稳定，这被结束非幽灵和真空盒子。最后，我们通过一些宇宙论的参数讨论模型的宇宙论的行为。
