When I lift the lid and the steam embraces me , I am six-years-old again with my cold red cheek pressed against the scratchy starch of grandma 's apron , and I feel warm and safe and loved . Here one lip of a webbed tube extends out in front of a silken burrow to serve as an apron of non-sticky threads . The MACS department has three degree programs available within the discipline of Mathematics : Traditional and Applied Mathematics , Mathematics Education , and Computer Science . For example , a ventilation system ( an engineering control ) reduces the inhalation hazard of a chemical , while gloves and an apron ( personal protective equipment ) reduce skin contact . Mathematics : The third of the University 's NSF Centers of Excellence on this list , Mathematics at LSU built over the course of three decades between 1950 and 1980 an outstanding reputation in pure mathematics . Dorothy put on a green silk apron and tied a green ribbon around Toto 's neck , and they started for the Throne Room of the Great Oz . The sixth in a series of workshops from the joint AMS-MER project , Excellence in Undergraduate Mathematics : Confronting Diverse Student Interests , is designed to highlight the resources and expertise within the mathematics community - - gained from running extra-curricular programs , and developing innovative courses - - for fostering students ' mathematical thinking , and challenge departments to adapt these ideas to mainstream undergraduate mathematics . A lead shield or apron may be placed under your genital and pelvic areas to protect them from X-ray exposure if it does not interfere with the test . The second in a series of workshops from the joint AMS-MER project , Excellence in Undergraduate Mathematics : Confronting Diverse Student Interests , featured concerns for students seeking a non-traditional mathematics major . Students will work with the book Basic Mathematics : You Can Count on Yourself , a custom text for the University of Massachusetts Boston by Linda Falstein .
