9、arbon dating was developedinthelatel940s by physicist Willard F Libby at the University of Chicago An atom of ordinary carbon called carbon-12 has six protons (质子)and six neutrons(中子)in its nucleus(原子核)Carbon-14，or C-14，is a radioactive unstable form of carbon that has two extra neutrons .It returns

10、 to e more stable form of carbon through a process called decay(衰减)This process involves the loss of the extra neutrons and energy from the nucleus. In Libbys radiocarbon dating technique，the weak radioactive emissions(放射)from this decay process are counted by instruments such as a radiation detecto

11、r and counterThe decay rate is used to determine the proportion of C-14 atoms in the sample being dated .Carbon-14 is produced in the Earths atmosphere when nitrogen(氨)-14or N-14，interacts with cosmic rays(宇宙射线)Scientists believe since the Earth was formed，the amount of nitrogen in the atmosphere ha

12、s remained constant Consequently,C-14 formation is thought to occur at a constant rate Now the ratio of C-14 to other carbon atoms in the atmosphere is known Most scientists agree that this ratio is useful for dating items back to at least 50000 yearsAll life on Earth is made of organic molecules(分子

13、)that contain carbon atoms coming from the atmosphere So all living things have about the same ratio of C-14 atoms to other carbon atoms in their tissues(组织)Once an organism(有机体)dies it stops taking in carbon in any form，and the C-14 already present begins to decay Over time the amount of C-14 in th

The researchers also gave the students tests to tell whether the students believed that a math superstar had to be a boy. Then the researchers turned to the teachers: To find out which teachers were anxious about math, the researchers asked the teachers how they felt at times when they came across math, such as when readi
