Artificial Straight-lined obsession with Stress ⇒Natural& Radial way of thinking with fun!!! After our ancestors started to use letters and numbers 5000years ago, we have been enjoying the convenience of then and at the same time struggling with them. why struggle? The straight lines (straight ordered things) letters and numbers make you do so. Look at Lascaux wall paintings. Nothing is drawn precisely vertical or horizontal to the ground. There're some squares on the wall but bit slanted or some collection of very short lines drawn RADICALLY!! Nevertheless, our ancestors were very creative and artistic. Inside of Every living entity's brain cells (roots of plants too!) are composed of web-like structure like Mind map. That’s natural tendency for everything. Structure of Universe is also same. Cosmos started from Chaos. So did Life. Nature is Not straight. Human world is completely surrounded by Straight.! People evaluate everything straight. Look at table, buildings, notebooks. In this age of 6th extinction if I say exaggeratedly, but as Dr.Hawking warns that humanity will go extinct within 1000years, we have to get out of cognitive mental box surrounded by straight. One of the keys for our survival is the radial ways of thinking, again Not straight. Eliciting your thoughts in a radical way might help produce creative and innovative ideas for the next coming phase of Evolution. Radial Memo/Mind map is not a tool or solution but a wise choice for humanities and our Earth🌐 今から2万年程前に描かれたとされるラスコーの壁画には散在する創造的な絵柄は多く見受けられるが地面に対して直線平行的に”列記”されたものはない。"放射状"に単線で表出されたものはある。更に今から5千年程前に文字、その後数字が登場すると同時に直線的な記載法が普遍化したと思われる。脳への負荷チャレンジの歴史が始まった瞬間である。創造領域を再び広げるため脳の負荷低減を実現するのが放射的思考といえよう。
