thermal referral

When warm thermal stimulators are placed on the ring and index fingers of one hand, and a neutral-temperature stimulator on the middle finger, all three fingers feel warm. This illusion is known as thermal referral (TR).

AxisAngle to Quaternion

qx = ax * sin(angle/2)
qy = ay * sin(angle/2)
qz = az * sin(angle/2)
qw = cos(angle/2)

where:

the axis is normalised so: ax*ax + ay*ay + az*az = 1
the quaternion is also normalised so cos(angle/2)2 + ax*ax * sin(angle/2)2 + ay*ay * sin(angle/2)2+ az*az * sin(angle/2)2 = 1

// assumes axis is already normalised
public void set(AxisAngle4d a1) {
  double s = Math.sin(a1.angle/2);
  x = a1.x * s;
  y = a1.y * s;
  z = a1.z * s;
  w = Math.cos(a1.angle/2);
}

말본새가 거칠다

서당개 삼 년이면 풍월을 하더라고 호령 소리 하나로 행세하는 수령 밑에서 뼈마디가 굳은 놈이라 말본새가 제법 가닥이 잡혀 있었다. 출처 : 송기숙, 녹두 장군

LIBOR

LIBOR는 London Interbank Offered Rate의 약칭이다. 런던의 유로금융시장에서 우량은행이 다른 은행에 대출할 때 적용하는 금리 즉 런던의 은행간 대출금리를 말한다. 국제금융시장에서 기준금리가 되고 차입자는 그의 신용도에 따라 LIBOR에 일정한 가산금리를 더하여 차입금 이자를 지급한다.
