 Children's Art Has Its Own Logic

Even simple scribbles are meaningful. While it was once thought that kids only scribbled to experience the physical sensation of moving their arm along the page, “now it’s been shown that when children are scribbling … they’re representing through action, not through pictures,” said Boston College’s Winner. “For example, a child might draw a truck by making a line fast across the page and going ‘zoom, zoom,’ and so it doesn’t look like a truck when the child is done, but i...

This reminds me of Sagan's pumpkin-carving, where he made random cuts and took out chunks to make it scarier with more "bloody guts."

 One in 1,000 to 500 Chance of Cancer from Childhood CT Scan

The first study to assess directly the risk of cancer after CT scans in childhood found a clear dose-response relationship for both leukemia and brain tumors: risk increased with increasing cumulative radiation dose. For a cumulative dose of between 50 and 60 milligray or mGy (mGy is a unit of estimated absorbed dose of ionizing radiation) to the head, the investigators reported a threefold increase in the risk of brain tumors; the same dose to bone marrow (the part of the body responsible fo...

 1.9 Cases of Leukemia per 10,000 CT Scans in Children

In the breakdown of results, the study authors from Group Health Research Institute and University of California, Davis note that the risk of developing leukemia was highest from head scans for kids under age 5 with a rate of 1.9 cases per 10,000 CT scans. Younger children and girls seemed more susceptible to solid cancers than older kids and boys. Every 300 to 390 scans of a girl’s abdomen or pelvis was associated with the development of one solid cancer. The study estimates that 4,870 fut...

 Parenting is Responsibility Without Power

Raising children is an intrinsically difficult and uncertain job in ways that science can't really address. For most of us parents there is literally nothing more important than the well-being of our children. There are not many things we could imagine giving our lives for, but we could give our lives for them. And, in a less melodramatic way, of course, we do give our lives for them. For fifteen or twenty years our everyday energy, our individual liberty, our income, our attention, our conce...

The parent's job is to be completely responsible for the child, but ultimately raise them to be completely autonomous, rendering the parent powerless over them.

 Piaget's View on Child Learning

Piaget concluded that babies aren't just born in possession of adult knowledge, either from a past life or from DNA. Instead, Piaget thought that children must have powerful learning mechanisms that allow them to construct new pictures of the world, pictures that might be very different from the adult picture. When we learn about the world, when we do science. for example, we don't just hit the right answer once and for all. Rather, there is a very gradual unfolding sequence of corrected erro...
