Why Can’t We Walk Straight?

When we’re blindfolded, we’re doomed to walk in circles. The same thing happens when we drive and swim without the benefit of sight. Around and around we go. Robert Krulwich, the cohost of the excellent Radiolab show (iTunes - FeedSite), breaks this all down with some intriguing animation. But let me add this little spoiler alert. What makes us spin in circles still defies scientific explanation. H/T to Mike in Cambridge.

    WOW! That’s amazing – I knew that in forest almost every person head always a bit right, but I didn’t know that this happens even while driving a car! Fantastic! However explanation needed -why scientist haven’t figured why yet?

    The video doesn’t reveal the reason for the question but for me it may be a centrifugal force of human while he/she blindfolded
